Wbengine.exe taking all CPU

Im having issues with wbengine.exe I know its the block level backup for WSB however its killing my server (see below) we are running on 2 x 600gb R1 SAS 15k disks for where the os VM is stored and 3 x 1tb nearline 1tb disks 7.2k where the data for essentials
("server folders/folder redirection" is stored with another virtual server doing very little in the background there is plenty of memory and cpu for all vms (just the two)
we have a backup on the vm start at 8 and finishes around 10 and a host backup that starts at 11 and finishes around 1
backups locally from WSB dont show to of started however they did on the host with warnings any ideas ?
UPDATE:
After talking to some users the issue occurred on yesterday morning, it looks like WSB is causing issues backing up when on schedule, as looking at the CPU usage from 8 at night last night. Thats when it started maxing out and the backup began, a single
one off backup seems to work fine using the settings of the schedule but scheduling seems to kill it.
To note this is going through ISCSI

Hi,
Glad to hear that you have solved this issue and thanks for sharing your solution in the forum. Your time and efforts are highly appreciated.

Ifweb60.exe takes all CPU on webserver-Forms Prod. mgmt

I have 3 tier setup. Database 81741 on windows2000 SP3. Webserver on windows2000 SP2 using forms6i patch 11(6.0.8.20.1). Clients using IE5.05/IE6 to access database. Sometimes, a user hangs the process and kills his session from his PC, even reboots client. The process is still there on webserver and goes on taking more CPU and more memory till it cloggs the webserver. It has taken almost 100%CPU. How can we eliminate this process without rebooting the webserver.
I tried killing the session from the database end, it is still there on webserver. The user says he waited for 2 mins to respond the application and then killed using ctrl-alt-del. Is there a way to kill the session on the webserver. When we try killing using Task Manager, it says 'access denied' and wouldn't let us kill. Even, tried with FORMS60_TIMEOUT. IN normal situation, this worked but in this case where a application hanged & user killed, FORMS60_TIMEOUT even didn't kill the process ifweb60.exe.
Someone has a idea how to prevent from rebooting webserver again and again...other than to check all 100 forms for any infinite loops and fix that.
Thanks a lot.

I believe this is a known bug.
As a work-around you could try to add FORMS60_CATCHTERM=0 to the registry.
This probably will cause Dr. Watson on the webserver box, but should kill the process.
Slava.

Server Process taking all CPU time intermittently on Solaris

Hi,
What does my program do :-
We have been facing this problem from many days, We have a server
process which is continuously listening at a port on Solaris 5.8.
Whenever a request is sent to this server a new thread & a socket is created for that client.
This process is running as a proxy server, which connects to some other machine on client request.
Problem:
The process start taking whole CPU after few days, happens in a weeks
period. The process remain in this state for few hours & after that it
stops responding to any requests.
& the only thing which can be done, to make it work is to restart the
process.
If someone has faced a similar problem then please let me know if you
have found a solution for that.
I will give 10 duke dollars to you if you can provide a solution for this problem.
Regards,
Sachin

Webcached.exe uses all CPU on IAS server

Hi, I'm having trouble with a process called webcached.exe according to Windows task manager, this process takes all available CPU resources, so our IAS server hangs. Anyone why this is? Any help highly appriciated! I'm pretty new to Oracle Application server, and have not experienced this before...
Is there a way to "go around" web cache until this issue is resolved, i.e. not use cache for a while perhaps? Longer responses are better than complete hangups....
I've tried to just stop the webcache process, but this apparently is not the way to go...
Windows server 2003 + IAS 10g (9.0.4.1.1)
Tor

Your post is a while ago... but you should upgrade Web Cache to 10.1.2.3, or install it in a separate location and configure it against your backend application. This is supported.
Webcache 9.0.4 is known to have some performance issues :)

OAS 4.0.8.1 wrksf taking all CPU

Hi,
My configuration is: NT SP6a, Oracle 8.0.5, OAS 4.0.8.1. All running on the
same server. OAS and Oracle 8 are in the same ORACLE_HOME. Whenever I
start OAS from the admin site, the WRKSF (catridge server) process takes up
100% of the CPU.
Could someone advice me how to trouble shoot this. Is there a fix? Pls ask
me more info if you need to.
Thank you so much.
-Julian

My experience with wrksf, on Mandrake 7.0 (RH 6.1+) is that wrksf starts at first, then bails after about a second.
I have a couple cartridges installed, C and Perl, and it starts those cartridges up and then fails. I don't get the same error message that you do, but there is an error in the wrb.log:
`OWS-10911: Throwing exception for reason: wrkpGetProperty 2 `
`OWS-04793: Operation oracle_OAS_System_CartridgeServerFactory_create_nwreturns exception IDL:omg.org/CORBA/UNKNOWN:1.0 `
I'm not sure what this is all about, but it does start up my cartridges at first, because I specified a mininum number to start up initially, and a minimum number of instances.
They just don't come back if terminated, since wrksf isn't there.
BTW, this is the same error I encountered when, on NT, I compiled a c cartridge with Metroworks CodeWarrior instead of MS Visual C++ v6.0. So I wonder if this has something to do with compiler incompatibility, if wrksf was compiled with a different compiler from the rest of OAS. While compilers don't usually matter for C, they do for C++, and all binaries and libraries must be compiled with the same compiler/linker to work together.
Just a stab in the dark.

Nissanlvd.exe taking up cpu usage primecoin

the only reference I saw to this file was on an italian forum. His symptoms mirrored mine. nissanlvd.exe running taking processing power. We have narrowed it down to primecoin miner being run and making connections outside our network. has this hit anyone
else..could this have been addon software..there is no add remove program for primecoin. We strengthened the firewall and the connections have stopped and the process has not started again. Will reboot this weekend to see if it comes back.
Would like to know if anyone else has seen this?
Is there a way I can tell for sure when it was installed and by who?
Thanks

the other possibility is that someone in our org was trying to mine primecoins..we were familiar with bitcoins but there were numerous wallets under the jackson directories for primecoin. The other thing is that an EULA asked to install the product
and someone said yes. Since we hardened the firewall there is no weird activity on that server. It just seems peculiar that the only references to this are one Italian forum and our system. There is no issues with other servers on the network. There is a distinct
possibility that we were hacked/invaded. I will reiterate that it seems weird that this isn't more prevalent if we were hacked..even on our own network. We are taking a slow approach to this but any other suggestions or advice would be appreciated. Thanks.

Since i up graded to itunes 10.5.2 i cannot access itunes store fully ,i have apple mobile device exe eating my cpu at 97% and now i tried to sync my ipod and it said that i needed to restore my ipod ,this i did and now i cant access my ipod library

this has got ridiculous now i cant access itunes tore,my ipod says there is no music on it even though i watched it sync nearly 5000 tunes and the program apple mobile device exe eats my cpu at 97% it slows my computer to a crawl should have had the courage of my convictions and stuck to itunes version9 at least that worked.tried resetting netsh winsock,flushing my dns all not worked.this has to be sorted out...and quick

Hi,
I have tried and confimed that you can download the previous version from some web-site about the version 10.5.1.42.
Remove/un-install 10.5.2.11 and restart your computer.
Install the old version 10.5.1.42
and then you can find the "Devices" on the left column and showing synchronizing when you connect the cable.
Good luck

Plugin-container.exe is EATING cpu clock cycles and slowing down my computer big-time. Is there a fix to prevent this, or do I just have to disable this subsidiary program and take the consequences?

Whenever I have an audiovisual display running in a Firefox (5.0) tab, the program "plugin-container.exe" swamps my CPU, jumping up to 95% of processing clock cycles. This makes all online video displays hang and jump, and it's a pain in the neck. Is there any way to mitigate this?

That's supposed to indicate it's your plug-ins like Flash that is the problem.
You might try changing hardware acceleration, a setting within Flash either turn if off or on.

Oracle.exe consuming 100% CPU on windows and database hang

Hi all,
every time my oracle database is hanging when the application run, the problem is the oracle.exe consum 100% CPU but not memory and the server hang and the dabase is going to inaccessible, we need to restart oracle instance service or server to bring the databas eback to normal but it's not permanent because the problem occurs once the application turn on.
Checking the log file i found the below error every time:

Is this a new application on this database?
Has it run well in the past?
I have had this happen before on a 32bit Windows server. Our problem was a poorly written procedure that kept pegging the cpu to 100%. You should be able to figure out what SQL is being used that is causing this problem, it will be the Top Working SQL most likely.
I also had this problem on a Logical Standby server which was trying to apply SQL to the SYS.AUD$ table. As soon as SQL Apply was started, the CPU went to 100%. Once I truncated that table, the cpu usage went back to normal. Not sure what you are using to monitor your database but if you can, try to find out what SQL is running when your CPU goes to 100%.

Procedure is taking 100% cpu

Hi ,
One of my procedure is taking 100% CPU, I looked execution plan .. But I am not sure what to look on that .. I didn't find any anything wrong in execution plan. like all are index seek .. Even the query is not taking much time just 2 sec
Regards Vikas Pathak

In addition to great suggestion Sean has been posted , I always start with the below
---This first thing to check if CPU is at 100% is to look for parallel queries:
-- Tasks running in parallel (filtering out MARS requests below):
select * from sys.dm_os_tasks as t
where t.session_id in (
select t1.session_id
from sys.dm_os_tasks as t1
group by t1.session_id
having count(*) > 1
and min(t1.request_id) = max(t1.request_id));
-- Requests running in parallel:
select *
from sys.dm_exec_requests as r
join (
select t1.session_id, min(t1.request_id)
from sys.dm_os_tasks as t1
group by t1.session_id
having count(*) > 1
and min(t1.request_id) = max(t1.request_id)
) as t(session_id, request_id)
on r.session_id = t.session_id
and r.request_id = t.request_id;

Wbengine.exe faulting, ntdll.dll module at fault

Hello All,
I've got a client with a WD Sentinel running Storage Server (Server 2008 R2 based). We setup Windows Server Backup and it worked for a couple of backups. We then added a second drive and encrypted both with Bitlocker. Now, I'm getting the following
error in the logs. It happens right after the volume shadow copies are created, when the dialog box says "preforming consistency check." There are no other errors that I can find. Any thoughts?
Faulting application name: wbengine.exe, version: 6.1.7601.17514, time stamp: 0x4ce79951
Faulting module name: ntdll.dll, version: 6.1.7601.18247, time stamp: 0x521eaf24
Exception code: 0xc0000374
Fault offset: 0x00000000000c4102
Faulting process id: 0x1e4c
Faulting application start time: 0x01cfacd6a8c1e15b

I did see that website, and have checked for any extra software. The Western Digital and Intel softwares are the only ones loaded.
While the behavior is quite similar to the error that is described there, it's not exactly the same. The fault offset and process are different. I've started working with Debugdiag to get a better idea of what is really going on. Here's the output from the
latest crash after I've installed all applicable hotfixes:

Dbms_stats.cleanup_stats_db_proc taking more CPU time.

Hi All,
Oracle 11g R2(11.2.0.3) EE , on Linux machine.
Oracle auto optimizer stats collection enabled in our environment. In that dbms_stats.cleanup_stats_db_proc() taking more CPU time (more than 24 hours).
Could you please suggest any solution.
Thanks in advance.
BR,
Surya

please let me know why it taking more time in INDEX RANGE SCAN compare to the full table scan?Suresh,
Any particular reason why you have a non-default value for a hidden parameter, optimizercost_based_transformation ?
On my 10.2.0.1 database, its default value is "linear". What happens when you reset the value of the hidden parameter to default?

SQL Developer occasionally hogs all CPU resources

Client OS: Windows XP Professional
Connecting to : Oracle 9.2.0.3 on Sun Solaris server
I encountered a few instances where SQL Developer hogs all CPU resources on my Windows XP notebook.
I usually have to kill the SQL Developer process.
I have noticed this happening occasionally when I :
1. hit Enter at the SQL Worksheet window
2. hit F9 at the SQL Worksheet window - the query does not start
How do I collect a dump or some kind of debug information when the above happens ?
Who can I send the information to ?

How do I collect a dump or some kind of debug
information when the above happens ?Start SQLDeveloper using sqldeveloper.exe in <sqldeveloper>\jdev\bin
When sqldeveloper starts hogging cpu, go to the console window and type ctrl-break. You should get a thread dump.
Who can I send the information to ?If you have a support contract, you can raise a TAR, otherwise post the thread dump here.

F1 live timing taking 100% CPU

I realise this is a pretty obscure problem. F1's live timing service runs as a Java applet in a browser: http://www.formula1.com/services/live_t … popup.html (registration required, but it should load and run at any time, not just on race weekends). Obviously, I haven't used it since last October, and when I fired it up this weekend it just sat there, taking 100% CPU.
It doesn't seem to be the JVM at fault: other Java applets run fine, and I've tried downgrading to a version I know worked last year. Neither is it anything in the applet itself: I have another Arch partition which I cloned off this one last November, and it works perfectly there (it doesn't seem to be the kernel, either; I tried booting this "current" partition with the kernel from that one). However, so many packages have been upgraded - and I've tinkered so much with this install - since then, that it could be literally anything.
For that reason, I don't expect anyone to come up with an immediate answer, but I'd appreciate some ideas on how to narrow down the possibilities and figure out what might be causing this.

Weirder and weirder, then.
