CSS 11501 100% CPU
I have a CSS running at 100% CPU with no services up. I cannot ping the CSS interfaces after about 1 minute of up time. Im running 8.1. Any ideas? I turned logging back to default and turned off my ACLs.
you'll need to go in llama/debug mode and do the following
symbol-table load SPRITZ
shell 1 1 spy
shell 1 1 spyStart
shell 1 1 spyReport
shell 1 1 spyReport
shell 1 1 spyStop
symbol-table unload
Do this when the CPU is high.
This will tell us the cause.
Also, if you only see the problem when logging is set to debug, then I would say do not set the level of logging so high unless you are trying to debug an issue.

High CPU utilization on CSS 11501 version sg0750303
Hi everyone,
I have the problem about High CPU utilization on CSS 11501 version sg0750303.
Our customer has used one pair of CSS 11501 (active-standby).
As a matter of convenience, called "Old CSS" after here in this post.
However traffic via Old CSS had been increasing so customer decided to add one more
pair (active-standby) of CSS to separate traffic.
Yesterday we installed new two CSS 11501 version sg0750303 (active-standby).
As a matter of convenience, called "New CSS" after here in this post.
Today, active CSS 11501 and standby CSS 11501 which were installed yesterday (New CSSs)
indicates High CPU utilization.
Active CSS 11501:
Peak CPU utilization: about 85%
Average CPU Utilization: about 60%
Standby CSS 11501:
Peak CPU utilization: about 40%
Average CPU Utilization: unknown
I do not understand why CPU utilization of both New CSSs become high.
The traffic pass through New CSS less than Old CSS, because the traffic is separated into
Old CSS and New CSS.
And CSS's configuration parameters (service, content, access-list) also less than Old CSS,
because real servers are also separated into Old CSS and New CSS.
Old CSS indicated average of CPU utilization about 20% before installing New CSSs yesterday,
in spite of all traffic pass through Old CSS only.
I wrote "New CSS remains High CPU utilization", however end users do not feel the
performance issue (e.g., performance delay, communication failure and so on) and
the traffic pass through New CSS normally.
So I have the question "CSS 11501 sg0750303 remains High CPU utilization on normal situation ?"
And customer uses MTRG to poll SNMP for Old CSSs and New CSSs.
So I have the question "CSS 11501 sg0750303 become High CPU utilization in case of receiving
SNMP polling ?".
Or if this situation is abnormal we need to start investigation.
Would you please let me know how do we investigate this situation.
I found the DDTS CSCek57080 "Performance issue using arrowpoint-cookie with ASR".
Release note of this DDTS says that
A customer was using a CSS pair configuration where arrowpoint-cookie
is being used along with a redundant-index on many content rules. When
the flow rate increased to a few hundred flows/sec, the peer message
queue of the CSS receiving ASR related message began to fill up.
When the peer message queue became over subscribed, the CPU increased
and the CSS became unstable.
New CSSs have configured redunrant-index on two content rules, and end users do not feel the
performance issue (e.g., performance delay, communication failure and so on) and
the traffic pass through New CSS normally.
So I think this DDTS does not related to this case.
Your information would be greatly appreciated.
Best regards,Gilles,
Thank you very much for your cooperation.
I got the capture you instructed us.
The following are additional information from our customer.
At time user traffic path through the active CSS, active CSS indicates;
CPU utilization always range of 30% - 40%
Peak CPU utilization about 60% - 80%
At time there is no user traffic pass through active CSS, active CSS indicates;
CPU utilization always range of 0% - 5%
Attached files are named "Active CSS.log" and "Standby CSS.log".
"Active CSS.log" is captured on active CSS and "Standby CSS.log" is captured on
standby CSS.
I found the following process is using resource by looking the output of
"shell 1 1 spyReport" command.
On active CSS,
tFlowMgrPktR 8ba24070 50 26% ( 1469) 20% ( 26)
On standby CSS,
fmPeerMsgTas 8a511510 50 16% ( 176) 10% ( 7)
Your comment would be greatly appreciated.

Do I need a live internet/DNS environment to test this switch? I have bridged vlan2 to e1. my VIP is set to X.X.X.47 and I have to services set to X.X.X.45 and .46. They both say active. The e1 port is up but my vlan2 is down. I am assuming that the circuit is my problem.
When you define a vlan IP address, the manual says that this is the IP address that the CSS will recieve traffic from, so that would be the virtual IP .47 that links to either .45 or .46 right?
I am suppose to configure 1 web server ip per port on the CSS switch? I currently connect the 2 web servers to a 8 port 10/100 switch and I have a straight ethernet cable from that 10/100 switch to port 1 (e1) on the css Switch.
Are all my port numbers suppose to be configured to 80 since they are being used for HTTP? Am I to use the HTTP keepalive function as well?
I guess any additional info would be great. I guess this isn't a click, click, and go switch like someone said.Ok. Thanks for the tip on the examples. I have tried to follow them as much as possible and have made progress, but I am still having problems with a few things that i can;t seem to find answers for.
CSS 11501 = IP 10.0.0.49 Subnet 255.255.255.0 Gateway 10.0.0.1
Srv01 = IP 10.1.0.45 Subnet 255.255.255.0 Gateway NONE
Srv02 = IP 10.1.0.46 Subnet 255.255.255.0 Gateway NONE
Dell 2708 = IP 10.0.0.13 subnet 255.255.255.0 Gateway 10.0.0.1
Client = IP 10.0.0.113 subnet 255.255.255.0 Gateway 10.0.0.1
I have Srv01 and Srv02 plugged into the CSS 11501 with IP address listed above. They reside in e7 and e8.
I have a cable from e1 to the dell 2708.
I have a laptop with a cable to the dell 2708.
I have configured a vlan (VLAN10) which includes ports e7 and e8 with an IP interface of 10.1.0.1. Status is active (GREEN)
I have configured two services with Srv01 and Srv02 and the status of both are active (Green)
I have created a content rule which includes both srv01 and srv02 with a VIP of 10.1.0.25. Status is active (green)
So I go to one of the web servers that is plugged into e7 or e8 and I can ping 10.1.0.25 sucessfully on both boxes. But I can only ping each servers IP address on its own box. In otherwords I can't ping cross server. When I try to access 10.1.0.25 from the servers the page doesn't come up. I know the VIP works because I can ping it.
I have also configured a VLAN (VLAN5) for e1 which goes to the dell 2708 with an IP of 10.0.0.48. But the status is down.
I am doing something wrong and can't seem to figure it out. any suggestions? I can diagram a picture in visio if you need a visual aid. I might consider Cisco University after all this. -
Why does iTunes use 100% CPU all the time, hogging my Macbook Air?
Decided to post this here instead of the iTunes forum, since it might be related to hardware too.
New owner of a 2011 13" Macbook Air, core i5 based.
My problem started about 1 week ago, after it had run out of power completely one day. At the first boot after that it was incredibly sluggish, totally unusable. After waiting for 5 minutes and still being unresponsive, I turned it off and then back on. Then it booted fine. HOWEVER, ever since that time I noticed the following behavior:
- iTunes stays at 100% + CPU all the time, mostly between 100-120%. Even if it's not playing. Even when I deleted the entire library and left it empty.
- iStats reports CPU idle between 50-65%. However, CPU temperature is still about 55 degrees C (which, I think, is far less than what it should have been with 50% idle cpu). I can confirm the low temperature by touching the chasis.
- the cursor freezes and jumps every few seconds, making the mac kind of unusable with iTunes open.
This has been going on for 2 weeks now. The problem goes away every now and then (iTunes sometimes goes back to regular CPU usage of 3-5%), but most of the time it's there.
Help!
P.S.
Mac OX X 10.7.2
iTunes 10.5.2Cee Pee You, is a OS modification. Apple recommends that you un-install these prior to a OS update because Apple makes changes to the OS all the time which breaks programs like these.
I avoid Unsanity LLC products like the plague. Notice the company is a Limited Liability Corporation (LLC), which makes it difficult to sue the company in case of a defective or malicious product. So the risk using their products is all yours. Their APE framework modules have been used for malicious purposes because anyone can write a module that uses the APE framework.
I also avoid installing anything that requires a administrative password unless I completely trust the source, like Apple mostly. That admin password is the key to the security of our machines, not to be given out lightly or carelessly.
You'll have to contact Unsanity's [email protected] because what I'm reading online is it's very difficult to remove as it doesn't "exist".

I am having a problem with Lightroom 5 being very slow, utilizing 100% CPU, then freezing or closing the program. How do I fix it?
I just upgraded to LR5 from LR3 on Sunday as well as CS6 from CS5 (which I have not tried out yet). I spent several hours talking with Vamil, from LR Support Staff yesterday. He was extremely helpful and kind and tried everything he could think of while remote-handling my PC and talking with me on the phone. He deleted preferences, cache, temp files, updated graphics with a new replacement file from AMD site, then re-downloaded and reinstalled LR5.
It is still very slow and then freezes and closes down with a message of utilizing 100% CPU. Within several seconds of using the brush in Develop, I started having lots of problems. I could not even move the picture around. The side screens would not disappear like they should. And I could not move to another picture. The day before I spent several hours trying to work on just 1 picture. After all the changes yesterday, I tried to move from picture number 1 to about 130 after having not touched it for 10 minutes, and a half hour later, it still said, "Processing" with no picture coming up, just a blank prieview pane.
LR Support suggested I get a new CPU though he thought according to specs mine should be ok and other programs were running fine.
My PC is only 2 years old.
I talked to HP briefly about CPU updates for my HP PC. He said I probably do not have a problem but suggested I run self-diagnostics and maybe buy a new CPU anyway.
I ran diagnostics listed through the HP Support Assistant connection on my PC. All was ok.
I still researched if I could buy a compatible CPU upgrade. I cannot even find any CPUs still selling that are listed for my PC. Best Buy Store said they could not even order a compatible CPU. They said my Bus speed may not be big enough, so they suggest I get a new PC. What Bus speed do I need?
I have the following PC Setup:
AMD Phenom II X6 1045T Processor 2.70 GHz with 6 Cores
with 2700 MHz Base, 3200 MHz Boost, and 4000 System Bus Speed, and 95 watts;
HP Pavilion Elite, HPE-500y, 900 GB Free, new in 2011;
Windows 7, 64 Bit;
RAM 16 GB, DDR3;
Graphics AMD Radeon HD 6450;
Nikon, D200, with Raw Files;
External Hard Drive for Original Photos, 600 GB Free;
LR Catalog and Library are on Main Hard Drive;
Monitor, Sony CPD-200ES, new in 2004.
I am thinking of buying a new monitor tonight mostly so I can do better photo work while enlarging the pictures to do it. I am concerned that while it will help my viewing, it will take more power away, and make my usage of LR5 even worse. Will a new monitor affect my performance? I am looking at HP Monitors with IPS. Is this the best recommended choice for LR and Photoshop CS6?
I think I would like to stay with a 6 core processor since I need to have several items open for other non-Photoshop functions. When running LR5, I had everything else closed. With LR3, I was able to have other things open.
I do not really want to buy a new computer and know that those I have talked with at this point are only guessing after looking for what they thought should fix it. 4 People from Lightroom Support have all thought I should not be having problems with my setup.
I bought one of the best computers 2 years ago. Is it really obsolete already so that I cannot use LR5? Is everyone else buying a new PC every 2 years? I used to go 5-7 years.
Even though I have figured out some of what my PC has, I really do not know technically what I am talking about so am at the mercy of other's help. Are there any solutions that might work short of buying a new computer?
I also have taken 40th anniversary photos for some people and am waiting to give them as a free gift since I am not a professional at all. I am hoping to get through this problem soon so that I can provide some nice memories for them.
I have not gotten any further than trying to adjust 1 picture. I have no comments on uploading speed, since I did that while still in LR3.
Thank you for your time and help.I'm running LR with no speed issues on an Intel 17-860 quad core with about the same performance as your AMD Phenom II X6 1045T Processor. My system is also an HP, which originally had a single 1TB 7200 HDD. I've since added a second 2TB Black Caviar HDD, which provided no significant difference in LR's performance.
AMD processors do not implement hyper-threading and don't need it. I'd start debug by process of elimination:
1) Disconnect all externally attached USB, FireWire, or other externally connected devices except keyboard, mouse, and your single 1280 x1024 display. This includes all externally attached memory card readers, phones, ipads, etc.
2) Reboot and logon as Administrator.
3) Remove your Internet connection and turn off all Antivirus and firewall programs.
4) Open LR and under Catalog Settings set 'Standard Preview Size' to 1440 (slightly larger than your display width). Under the Metadata tab here make sure 'Automatically Write changes into XMP is NOT checked.
4) Create a 'New Catalog,' Create a new folder and add about 10 raw image file copies to it for testing, and Import it into the new catalog. In the Import module make sure under File Handling 'Render Previews' has 1:1 selected. Wait until all Preview building has completed in the Library module.
Try editing these image files inside the new catalog as you were previously. -
Queue consumer stops with 100% cpu usage
I'm trying to use Berkeley DB queue with transactions. When I tested what happens when transactions with DB_APPEND are aborted I found that while it works and DB_CONSUME correctly skips over rolled back records, unfortunately extents that have those records are never deleted, which causes database to always grow. Next I tried DB_CONSUME with database opened using DB_INORDER flag and it seems there's a serious regression in Berkeley DB that causes it to loop indefinitely with 100% cpu usage when it encounters a rolled back record. I tested various versions and found that this bug doesn't happen with 5.1.29, but it is reproducible with 5.2.42, so this regression might have been introduced in 5.2. I have also tested 5.3 and 6.0, and both have this behavior. There may be something wrong with the way queue records are rolled back, one indication of that would be that in 5.1.29 doesn't have neither of the two problems I found with DB_QUEUE: extents are deleted after being consumed, and there are no issues when consuming with DB_INORDER either.
You can find Python code to reproduce this issue here:
https://gist.github.com/snaury/027a3c546f5b0a62a440
Sorry for using Python and not e.g. C++, but it's a lot shorter that way.We have looked at the issues and they are valid. We will roll the fixes out for this in our next release of BDB. The test case was very useful and really helped to speed the process up. If you have any questions, please contact me directly at [email protected] Thanks again for bringing this to our attention.

Hi all,
We've bought about ten pieces (HP LaserJet Pro MFP M127fn), tested only one the other 9 are waiting for their time to be sent in our branch offices. The MFP works fine, no complains till later that day I noticed that our Mikrotik Router was struguling with high CPU usage, it took me some time to find the issue and it was the new bought MFP. Don't know why but it creates hundreds of UDP connections and almost 100% CPU usage goes to DNS service. As soon as I shutdown the MFP and delete all the connections everything goes back to normal. I've disabled almost all services (HP web service, Ipv6, SNMP, AirPrint, SLP, LPD, WS-Discovery, Bonjour), leaving only Ipv4 but without luck the issue persists. Here are some print screens confirming my saying:

I tried to add this in the topic already open but it kept sending me through the unending rabbit holes!
My question is: How do I figure out what release I was on, get rid of this one and got back to a functional firefox that moves in realtime. I already did all the reset and etc.... I just want to go back to the speed I had. This halting , hanging up misery of a browzer is Sad. I have had firefox for years and always recommended it ..... BUT NOT ANY MORE. I agree with the other poster ... there should be a rollback feature. Peoples time has value and right now FireFox is sucking the value down a rabbit hole.
See Below Comment Feedback submitted before I finally got here:
This new version of FireFox is making me nutz! It is SUCKING 100% CPU time almost constantly. I could just pull my hair out. I wpdated once a month or so ago and it slowed down..... but the latest update before I did the reset really slowed me down. I came here to fix it a couple of dayz ago and did the reset firefox and now it IS RUNNING SO POORLY AND SLOW I AM ABOUT TO KILL IT OFF MY MACHINE!!! Yes that is me yelling - and it happened in SSSSSSSSSSSSS LLLLLLLLL OOOOOOOO WWWWWWWWWW Motion. I have run all the security scans and cleanups ---this needs a fix ASAP!!! PS: The hang ups and slowness is EVERYWHERE I go. I only get speed doing programs not connected to ON LINE.Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
Thank you. -
Whenever I click a link that is designed to open in a new window Firefox goes straight to 100% cpu usage and I have to go through the Windows "end now" sequence to close the program. I've tried opening one of the links in a new window but I think it was done in java not html (not sure if all the links are java when this happens as that's the only one I've tested). Not sure what details someone might need but this is on my Mom's older laptop with Windows XP Media Center Edition Ver. 2002 Service Pack 2. Hmmm just saw the SP2 will try to update and see what that does though I don't think that's the issue.
So what is happening or not happening now ? The problem computer is your Moms, but I assume your own computer works ok. Have you tried that on the same internet connection as your Mom uses & visiting the same sites?
Also try Internet Explorer. If that is also very slow the problem may not lie with Firefox.
I suggest you try the Firefox Reset feature on your Mom's computer,
* BUT first of all
**make a note of the software extensions that are in use, and bookmark their download and support sites.
** back up the Firefox profile [[Back up and restore information in Firefox profiles]]
* follow the instructions in the following article, after reading the caution about what will be lost
**[[Reset Firefox preferences to troubleshoot and fix problems]] -
How to reset password on Cisco CSS 11501?
Hi,
I have changed the password for the Admin user (which was SuperUser) but when I changed it I forgot to add "SuperUser" at the end, now I don't have SuperUser access to the CSS 11501.
Can anyone shade some light on this problem and explain how can I reset the password for a SuperUser?
Thanks in Advance,
ShaiHi Shai,
You need to reboot the CSS. When prompt, hit any key to go into the Offline Diagnostic Menu.
When you get in the menu, you will go to Administrative options and create an additional Admin user. When you do this, DO NOT use "admin", use something totally different.
Get out of the Offline DM and reboot the CSS. When the CSS comes up, login as the new user (which will have Superuser rights) and run the "username" cli to change the password of "admin" and add the superuser part this time.
Regards

100% CPU Usage Overhead running EM DBConsole 11g on OEL-5.2
After upgrading to OEL-5.2 and relinking all Oracle binaries, my old Oracle 11g installation, installed several months before on OEL-5.1, has been working well, including Enterprise Manager Database Console working nicely as always with respectful performance. Unfortunatelly, it lasted just several days.
Yesterday I decided to uninstall the 11g completely and perform new clean installation (software and database) with the same configuration options and settings as before, including EM dbconsole, all configured using dbca. After completing the installation (EM was started automatically by dbca), oracle continued to suck 80-85% CPU time. In further few minutes CPU utilization raised up to 99% due to only one (always the same PID) client process - "oracleorcl (LOCAL=NO)". For first ten minutes I didn't care too much since I always enable Automatic Management in dbca. But after two hours, I started to worry. The process was still running, consuming sustained 99% of CPU power. No other system activity, no database activity, no disks activity at all!
I was really puzzled since I installed and reinstalled the 11g at least 20 times on OEL-5.0 and 5.1, experimenting with ASM, raw devices, loopback devices and various combinations of installation options, but never experienced such a behaviour. It took me 3 minutes to log in to EM dbconsole as it was almost unusable performing too slow. After three hours CPU temperature was nearly 60 degrees celsius. I decided to shutdown EM and after that everything became quiet. Oracle was running normally. Started EM again, the problem was back again. Tracing enabled, it filled a 350 MB trace file in just 20 minutes. Reinstalling the software and database once again didn't help. Whenever EM is up, the CPU usage overhead of 99% persists.
Here is a cca 23 minutes session summary report taken from EM dbconsole's Performance page. The trace file is too big to list it here, but it shows the same.

----------------------------------------Wow!!! Note: no disk, no database activity !
Has anyone experienced this or similar behaviour after clean 11g installation on OEL-5.2? If not, anyone has a clue what the hell is going on?
Thanks in advance.Hi Tommy,
I didn't want to experiment further with already working OEL-5.2, oracle and dbconsole on this machine, specially not after googling the problem and finding out that I am not alone in this world. There are another two threads on OTN forums (Database General) showing the same problem even on 2GB machines:
DBConsole easting a CPU
11g stuck. 50-100% CPU after fresh install
So, I took another, a smaller free machine I've got at home (1GB RAM, 2.2MHz Pentium4, three 80GB disks), on which I used to experiment with new releases of software (this is the machine on which I installed 11g for the first time when it was released on OEL-5.0, and I can recall that everything was OK with EM). This is what I did:
1. I installed OEL-5.0 on the machine, adjusted linux and kernel parameters, and performed full 11g installation. Database and EM dbconsole worked nice with acceptable performance. Without activity in the database, %CPU = zero !!! The whole system was perfectly quiet.
2. Since everything was OK, I shutdown EM and oracle, and performed the full upgrade to OEL-5.2. When the upgrade finished, restarted the system, relinked all oracle binaries, and started oracle and EM dbconsole. Both worked perfectly again, just as before the upgrade. I repeated restarting the database and dbconsole several times, always with the same result - it really rocks. Without database activity, %CPU = zero%.
3. Using dbca, I dropped the database and created the new one with the same configuration options. Wow! I'm again in trouble. A half an hour after the creation of the database, %CPU raised up to 99%. That's it.
The crucial question here is: what is that in OEL-5.2, not existing in the 5.0, that causes dbca/em scripts to be embarrassed at the time of EM agent configuration?
Here are the outputs you required picked 30 minutes after starting the database and EM dbconsole (sustained 99% CPU utilization). Note that this is just a 1GB machine.

100% CPU using LabView 7.1 and DSC module
Seven years ago I used BridgeView and PXI to execute a project, and the results were so good that after that initial system, I installed one more using BridgeView, and three more using LabView 7.1.
BridgeView is working very well, but lately, LabView 7.1 is giving me more and more problems. It all started in a system running LabView 7.1 and DSC on Windows XP, using a PXI-8187 controller with a PXI-1042 chassis. I have two PXI-6533 digital I/O boards, one PXI-6030E multifunction, one PXI-6713 analog output board, one PXI-6602 counter board and one PXI-8422 serial com. board. In may/06, all of the sudden, the CPU went to a 100% use. Since I am running PID's to control a flash-butt welding machine in a steel factory, this was extremely dangerous. I changed the controller and everything went back to normal. It was running fine until december/06, when the same behavior appeared again. This time changing the controller did not help. We increased the system memory, from 256 MB to 512 MB and everything worked fine. But one month later (january/07) the fault reappeared. This time we changed the chassis and from that moment to this time, we are running smoothly.
Application problems were suspect from the very first time this problem appeared, but I was unable to identify the source, if any. I used PROFILE VI's and apparently the write/read tags were taking all the processor resources. However, changing the routines and disabling communications, and optimizing CPU intensive programs never solved the CPU overload.
Until now, I was aware of only one system showing this erratic behavior. But today I went to check another system, with a totally different application. This one is used to measure the thickness of the steel sheet on a rolling mill. Is not so resource-intensive, but the maintenance folks told me that every time they turned off this particular system, they always had problems trying to turn it on.
I was suspecting of a PLC-communication related issue, but what I found turned my alarms on. I turned off the system, which was fully functional, and turned it back on, and there it was, CPU load at 100%!. Is exactly the same problem that I have on the welder. This system has a PXI-8184, a PXI-1042 chassis, Windows XP, one PXI-6030E, one PXI-6713 and one PXI-6533. I battled for 20 minutes to put the system back in normal conditions.
I specified every single board, installed everything and programmed all the applications. The BridgeView applications have never showed anything like this. I am using the DSC (Datalogging and Supervisory Control Module) on both applications, and the Lookout Protocol Drivers are communicating to Modicon PLC's.
Please, I need help to solve this issue. I believe none of your actual Knowledge Base "100% CPU" articles apply to my case...
Thanks in advance...

[email protected]Thanks for your reply...
Yes, sometimes I have the feeling that the systems works again because some file or database gets initialized after so many reboots.
Intentionally I turned off all the events and alarm logging to disk. Also the historical data logging is disabled. This is done by code, every time the main VI is started. This was included precisely to save CPU processing power. However, I am communicating to PLC's, and of course I have to declare variables inside the citadel database to make the communication possible.
Right now I can't have access to the application, because the mill is rolling, but during the next maintenance stop I will check the database location and size, and I could change the directory location the next time the fault comes up. -
Sessions with Event "class slave wait" taking 100% CPU
Hi experts,
I have an issue in an 11.2.0.2 RAC database with 2 standby nodes that are driving me nuts.
All started when I've been told there are 2 Oracle processes consuming too much CPU in the environment.
I found 2 processes which takes 100% CPU each. These processes are Oracle processes into the DB and checking them out although they are registered in v$process and v$session, there is nothing related to them in v$bgprocess so I could not find out which oracle processes started these 2 OS processes.
The view v$session shows them ACTIVE in the event "class slave wait". There aren't too much information about this event, at least I failed to find...
Using dbms_monitor and dbms_system to create trace events did not create any tracefile. Only ORADEBUG was able to create events but with nearly no information inside the trace files.
Questions I need to have answered or at least hints that I can follow to find the answer:
1) what is causing the CPUs to be consumed at 100%? Which process?
2) Why does these processes are using that much of CPU?
3) What can be done to safely get over it?
Honestly I don't know where else to look at except trying to get some help. Could someone give me a hand please?
BR,
Lauro Ojeda
Edited by: LauroOjeda on 26/01/2013 06:44Hi Pal, thanks for your reply!
Here are the answers:
1. If it is RAC there is no such construct as a "standby node" and you say you have two of them. Please be specific ... is this RAC or Data Guard or a combination? Or do you have a three node cluster with all services pointing to only a single server wasting all of the resources of the other three?
A: This is a combination of them. We have 2 nodes in a RAC environment shipping logs to two physical standby databases in another site.
2. Two processes can not be at 100% of CPU any more than I can be 200% awake. Please show us how you arrived at this conclusion, on what hardware and operating system, and include a formatted (read the FAQ to learn how) extract showing what you are seeing.
A: top in Linux shows two oracle processes consuming 100% (or nearly of it) of 1 CPU each. This is a 16 cores server (each primary node) so 2 of these are working on full capacity to service the described processes.
3. What processes? Name them and again run a SQL statement and post the output so we can see what you are looking at.
A: Like I said before I failed to find which background process they belongs to as there are no indications of them in v$bgprocess and in v$session/v$process either. I can see them in v$process and v$session but again, there are no indications of for which bg process they belong to.
4. Is anything slow? Are there any problems with the system or are you only reacting to two numbers you think are too high?
A: No, system is not slow because of that but the client wants to investigate and have it sorted as it is not normal.
Additionally I found a bug in metalink which seems to be the culprit, but I'm unsure yet. This is Bug 12929268 : HIGH CPU ON ORA_O00N PROCESS
Is any other information that I may provide you?
Thanks for help!

Mail Can't Open & com.apple.internetaccount process hogging 100% CPU
Desperately seeking answers after Mavericks install..
My mail crashed and now won't open at all. I've tried most (if not all) the suggestions posted by others. Haven't tried deleting and reinstalling mail yet, as this will be my last resort since I have a work account in it that is not on IMAP.
And another troubling issue is my macbook's fan is going crazy and feels like its overheating.
Looking at "Activity Monitor" I see a process "com.apple.internetaccounts" that is taking 100% CPU and 1.6GB of memory!!
No idea what this process is and can't seem to quit it.
PLEASE HELP!!! Thanks in advance

840 KB Page-outs@Drewli77 yup that's it. When Mail opened I chose Google/Gmail and let Mail set the account up for me.
Before doing that I had noticed com.apple.internetaccounts hogging the CPU. I went into System Preferences > Internet Accounts, waited 10 minutes for the spinning ball to stop, then deleted the Google account in there. There was only one Google account in there, despite the fact that I have four Google accounts set up in Mac Mail. Anyway this one account seemed to be what was slowing down that preference pane. After deleting Accounts.plist I re-added my accounts in Mail, which added them to the Internet Accounts preference pane, but now that preference pane (and Mail) open just fine without hogging resources.
What annoys me is the fact that hitting Delete on a message sends it to Trash, which in Mavericks corresponds to Gmail's Trash, meaning it gets purged every month (regardless of the setting you choose in Mac Mail). I've been using Option-Delete to Archive it, but I wish I could just use Delete for that, since I always Archive and rarely Trash messages. I would set another folder to be used for Trash, but sadly, all of the options under Mailbox > "Use this mailbox for" are greyed out. -
Photoshop CS5 always around 100% CPU usage
Photoshop CS5 12.0.1 x64 running on Snow Leopard 10.6.4 always takes around 100% CPU, no matter if it's on screen or not. I can not figure out what it is doing behind the scene. I have deactivated fonts preview and I have no third party plugin except for the FontExplorer plugin (that handles missing font requests).
Use case example : Right now, Photoshop is hidden and on a different Space (as in Mac "Spaces"). The only open file is a psd file, containg only a few layer and groups, no text and is 240px X 130px. For the past 10 minutes, Photoshop's CPU usage has varied between 99.8% and 103%. This seems odd, comparing to After Effects running at the same time using only around 0.6% CPU...
Any idea how I can fix this?Try turning off font previews, try disabling your third party plugins.
We've seen several third party plugin bugs that would waste CPU time.
And font previews can spend time (completely interruptable) until the previews are completed.
Photoshop normally uses 1% or less CPU when in the background.
