One of our Jazz applications is hitting 60-80% CPU ( or higher ) and I see this list of Active Services:

User says just creating test cases, test scripts.....

Is the user using RQMExcelImporter to create the test artifacts? I wonder why the activity names all have "oslc" in them.


Kevin Ramer commented Sep 03 '14, 8:02 a.m.

I asked for usage and this was the response:

My OS : Windows 7 64bit
Browser : Firefox 31.0

[My Steps of using RQM]
1. Click my bookmark of RQM
2. Login to Quality Management (Quality Manager)
3. Open a Test Suite in new tab.
4. Open multiple testcases and test scripts in new tabs
5. Open new firefox windows with test cases or test scripts(maximum 3)
6. Modify or Copy test steps around
7. Sometime "Duplicate" the testcase or test scripts.

If you have sever performance concerns, please open a PMR.

At this moment, the UI for the application server in question is still quite responsive.  I can only associate the high CPU with the WAS java process which contains the QM application ( along with JTS, RM and CCM ).   So I cannot yet say we're to the state of performance concern.


Kevin Ramer commented Sep 05 '14, 2:45 p.m.

PMR 18660,L6Q,000 was opened.  Right now there are 29 of the aforementioned activites with durations of 17h to 4.5 days and growing. CPU use on our LPAR is at a steamy 97% constant for the last day or so.  I think I found a possible cause and have informed via the PMR and to our QM user.  

I plan to restart the QM application tomorrow.
