Ora_m000 consuming 100% cpu with ORA-00600 [kcbz_check_objd_typ_3], [0]

Hello,
I have been trying to troubleshoot high cpu usage in our Ebiz R12 environment where cpu is running 100% by ora_m000 process and I see ORA-00600 in alert log.
I have tried work around from metalink note 466049.1 and even applied fixed for patch 4430244, 5752105 but it hasn't fixed the issue.
Before going through opening a ticket with support, I thought try my luck here. I'd really appreciate any suggestions to fix this problem.

Why does my iWork update hang with zsh consuming 100% cpu?

The App Store updates for iWork Apps (Numbers, Keynote, Pages) have hung for me multiple times. After some digging, the hangs appear related to setting zsh as my default shell (Open Directory UserShell /bin/zsh). When an update is hung in App Store, Activity Monitor shows zsh is consuming ~100% cpu. Inspecting the process, it's hung on zsh -c defaults delete com.apple.helpd com.apple.helpd.sdmMapsCreated or something similar each time. If I kill the hung process enough times, eventually the update completes.
Most recently encountered updating to Numbers 3.5.2 on OS X 10.10.1 with $SHELL=/bin/zsh 5.0.5 (x86_64-apple-darwin14.0).
Possibly related to keynote not installing.
Definitely related to http://apple.stackexchange.com/questions/146919/zsh-using-100-of-cpu-during-iwor k-install. The workaround described here is the only way I've gotten through it.

You probably deleted something crucial to the stability of the operating system. I suggest backing up your important files, and doing a complete reinstall.

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.

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%.

Explorer.exe consuming 100% CPU after resuming from hibernation

I you have any clue what might be going, I would be very happy to hear it. It's really annoying, as I have to kill explorer.exe and thereby close all my folder windows when this happens.
Thank you!
Best regards,
David Trapp

Hello,
thanks for having a look. However, I already ran SFC before posting on this forum (as part of my own investigation) and it came back clean. RescueTime (a time tracking tool) is probably not the culprit because it happened also several times in the past without
RescueTime being running (that was because I had accidentally removed it from autorun at that time).
Unfortunately, I can't follow your "invalid date" explanation. I don't think an "invalid date" is anywhere involved; in fact, the method in question is called "_TreeInvalidateItemInfo" and not "_TreeInvalidDateItemInfo"
(note that there is only one "d"), so I assume its job is just to invalidate (and in turn, refresh) the cached information about nodes in the left pane's folder tree of the explorer window(s) - since the folder tree is the only NamespaceTreeControl
(whose corresponding class name is CNscTree) in explorer folder view windows. As I see it, something is causing explorer to repeatedly refresh the folder tree data, but I am stuck at finding out what exactly.
Best regards,
David Trapp
EDIT: Disassembling ExplorerFrame!CNscTree::_TreeInvalidateItemInfo confirms that, because it seems to call TreeView_SetItem for a tree node and its parent (possibly with all fields set to *_CALLBACK), and CNscTree::_UpdateItemDisplayInfo
for the parent node.
EDIT2: I'd love to dig more into the trace, however I am hitting a wall at function names/addresses. Everywhere where I would expect a function name/address (such as the "by stack" views), I only see question marks instead. What
could be the reason?

One boe_jobcd process allways consuming 100% CPU

Hi, I am running Crystal reports server XI R2 Linux on RHEL4
Normally we have from 1 up to 4 boe_jobcd processes depending on the "load" of our system, The processes seems to shutdown when not needed, But now one of the 4 BOE_JOBCD processes will never die and it is consuming 100% cpu...
Can I stop/kill the process? How ?

Dear Both,
I traced the RAS server as suggested by Tim and obtained a log that - I have to admit - is quite difficult for me to understand. Could I send it to one of you for examination? Thanks in advance.
Ted, please find below my answers to your questions:
Just to close out possible data source issues, are the reports going against Business Views or Universes?
The report is based on Business Views.
Do you have Processing Extensions specified for the reports?
Sorry but what are Processing Extensions?
Also, when you checked in the Crystal Reports Designer, was it Designer installed on the same machine where the page server and RAS server is running?
Yes, it is installed on the same machine.
Also, since it affects both Page Server and RAS, it may require CRPE traces to get to the bottom of this (CRPE - 'creepy' - is the CR engine used by both the Page and RAS server).
I will certainly open a case with SAP to have them help me on that.
Thank you both for your help. It is very appreciated.

BT NetProtect intermitantly consuming 100% CPU

Hi, I have Infinity install and all is working fine, I installed the BT NetProtect secuity software and find that every so often it suddeny consumes 100% cpu and my PC slows to halt for about 1 or 2 seconds. This happens randomly through the day sometime 20 times over an hour, sometime once every 4 or 5 hours.
At first I have disabled various functions such as the rteal time scanning etc but it still causing a problem. Uninstall the software and the problem is resolved - re-install and problem back again.
Watch the Performance monitor under the Task Manager and you can see the CPU max out when the problem is experienced.
Any one else with this problem and any ideas for a solution.
All help greatly received.
Steven

Without more detailed info I wouldn't like to guess on why it's using 100% cpu, sone older McAffee products that I have used have been pretty resource hungry but 100% dosen't sound right at all! Although I have never used it myself there are many good free alternatives.
I have tried many AV solutions and Firewalls on my Windows Machines over the years inc BitDeffender, Avast, NOD32, Avira, AVG, ZoneAlarm, ClamAV.
Until recently I was running Agnitums Outpost Pro firewall and Eset NOD32 antivirus. Both of which have been very good, NOD is a nice lightweight AV but it's not free.
Recently I switched to Comodo Internet Scurity Pro which is a free security suite containing comodo's excellent firewall which always rates highly firewall tests, and their equaly impresive AV system if interested you can download it here:-
comodo.com/home/download/download.php?prod=cis
Choose the free version its identical to the paid version but without GeekBuddy.
Also take a look at Avast Free or AVG free.
If all else fails try Linux

Wireportserver.exe is consuming 100% cpu

Hi Experts,
We are using SAP BI 4.0 sp6 windows for our BO Application.From last week onwards we are experiencing system freeze as the WIreportserver.exe consuming 100% cpu.we have to manually kill it to make the system work again.Even restarting the servers doesn't help!
Sometimes this issue happens when if there are no user logged in.Recently there are no changes made to the server.Hence not sure what
might be the reason behind this.
Thanks in advance for your help.
Regards
Kishore

I would request you to confirm the below steps.
1) If you are using Load balance then please increase the Load Balancer idle session timeout .
2) Can you also do this test: Please do take backup of the file.
1- Open folder : <Your BO install Folder>\Tomcat55\webapps\AnalyticalReporting\WEB-INF\classes
2- Edit file : webi.properties
3- Change the lines :
#WID_FAILOVER_SIZE=10
#WID_STORAGE_TOKEN_STACK_SIZE=10
By:
WID_FAILOVER_SIZE=0
WID_STORAGE_TOKEN_STACK_SIZE=0
4- Save ans close the file
5- Restart tomcat
6- check if the issue is resolved
3) Purge the query and run the same one by one. Once it is done then refresh all the queries. With this we can get to know which query is causing the issue. If you find that few queries are taking long time then foloow the below steps for that specific queries:
a. . Edit the report and go to Edit Query.
b. At bottom you can see the name of the Query
c. Right click on Query and click Duplicate Query. It will create a copy of the original query.
d. And then delete the original query.
e. Do the same step for all queries
f. Run all queries and then test the issue again.
4) Run the report in Webi Rich Client. If it works then Save the report with different name and in different folder. And export same in Repository. From the Infoview try to refresh the report.
5) Please check if using Web mode is acceptable workaround.
6) In Universe Designer> parameter> Controls, uncheck the option 'Limit Execution Time To' and 'Limit Result Set To' parameters. By doing this it will allow users to create queries that have not been tuned, run for extended period of time .
7) It is always recommended to Schedule the report which are of large size instead of refreshing. I would suggest you to schedule the report to resolve the issue.

"IMAQ Stop" takes 10sec to execute and consumes 100% CPU

Hi, I'm calling IMAQ Stop to end an acquisition but it consumes 100% of my processor and takes 10sec to complete (all the while consuming 100% CPU). In our application we start and stop the camera regularly and this is exactly when the user wants the program to be interactive so this 10sec delay is a big irritation to them.
My setup is - Dalsa Piranha line scan camera, RT 9 running on a desktop PC (it is compatible according to the test), PCI-1429 cameralink card.
Any help or comments welcome.
Thanks.
Solved!
Go to Solution.

Ah I have managed to solve this one, but first here are the answers to your questions:
Using Stop and then Close or just Close makes no difference. The Stop was taking so long that I simply used a probe before and after it on the error cluster and with 2009's probe timestamp function I could easily see how long it took. For more detailed timing analysis I use the us timer available with RT.
In any case, the way I solved the problem was by making sure that I stop the acquisition BEFORE the line clock to the camera is stopped. So IMAQ Stop probably waits for the end of the current frame before it returns - and if the line clock stops halfway through a frame (as was the case), a 10 sec timeout probably causes Stop to return eventually.
The line clock is being driven by a DAQ card (via RTSI) and I simply closed the session to that counter AFTER calling IMAQ Stop. The DAQ interface is not shown in the example above as it is coded in a different vi.
Thanks for all the help.

Some Oracle processes are consuming 100% CPU

Hi,
Some of my oracle processes are consuming most amount of cpu continuously.What are the general steps to sort out this problem.I think the query is a tuned one.

Hi,
What is your veriosn of Oracle? what is the OS? which oracle process is consuming 100% CPU? how did u find out it is conuming?
and you have mentiond query is tuned one... it does your query is taking time to execute?
there is no clarity in your question...

Oracle.exe is consuming 100% cpu o windows

Hi,
We have 6 oracle 10g database on windows box and from task manager we are able to see oracle.exe is consuming 100% cpu
Need to know this oracle.exe belongs to which database and can i get the sql for this process
Thanks

On my Vista PC, I find that the easiest way to identify which instance an oracle.exe is, is the task manager. On the Processes tab, right-click the oracle.exe and then click Go To Service(s) and that takes me to the OracleServiceORCL or whichever insance it is.
I'm sure there is a better way that a Windows person could tell us about. Then having identified the instance, it is just normal tuning from there.

CustomTableCellRenderer consume 100%CPU

I have a Table wtih a customTableCellRenderer. I �ve found out that the method getTableCellRendererComponent of my cellRenderer will be repeatly called. Thats why it consumes 100% Cpu.
Here the setting of table

          renderer.setForeground(Color.BLACK);
          renderer.setBackground(Color.WHITE);
          return renderer;
}thx for fast help

Do not construct a new Renderer everytime when your value is a instance of AppointmentStateIcon. A renderer just act as a rubber-stamp for rendering all cells in the table; it renders the first cell, changes the contents of that cell renderer, shifts the origin to the new location, re-draws it, and so on. Try to overrides the validate, revalidate, repaint, and firePropertyChange methods to be no-ops to help to increase the performance. Read the API Documentation for DefaultCellRenderer for more information.

Oracle 11g R2 consuming 100% CPU on execution plans

Hi Friends
I just installed oracle 11.2.0.1.0 on Windows 2008 Server R2.
I got 4GB of RAM = 2536MB for SGA and 600M for PGA
I'm running a processes that is consuming 100% of CPU ant its showed on execution plan of every statement this utilization.
I have worked with disk_asynch_io parameter to FALSE and had no improvement on performance.
Reading a doc relating to a bug I set up the dbwr_io_slaves to 4 but no changes.
Now I'm stuck on asynch descriptor resize wait event for more than 4 hours.
Any ideias os tips or experience about this issue?
Tks a lot

Well, Tks for your help guys,
The problem was solved "almost" at all by disabling MEMORY_TARGET and SGA_TARGET and setting up all the memory parameters manually.
This has eliminated the event "asynch description resize" and the overall performance of the DB has increased. I was able then, to complete my operation.
I believe its a Windows bug or a poor design or configuration of mine. But at this time we are able to run the system well and fast enough.
Tks a lot
