Re: Remedy 9.0.01 - CPU issue
Along with Java settings (Heap, GC, etc.) please check your min and max thread settings and make sure both are set to MAX. -Original Message- From: Action Request System discussion list(ARSList) [mailto:arslist@ARSLIST.ORG] On Behalf Of Su Kaur Sent: Friday, November 11, 2016 10:12 AM To: arslist@ARSLIST.ORG Subject: Re: Remedy 9.0.01 - CPU issue We already have following parameters set jvm.option.17=-XX:+UseConcMarkSweepGC jvm.option.18=-XX:+UseParNewGC Most of our users are still using Remedy User tool version 7.6.

Re: Remedy 9.0.01 - CPU issue
Check your garbage collector settings as well. We saw similar issues when upgrading from 7.5; that was the culprit. https://docs.bmc.com/docs/display/public/ars8000/JVM+runtime+analysis Respectfully, Anthony Floro -Original Message- From: Action Request System discussion list(ARSList) [mailto:arslist@ARSLIST.ORG] On Behalf Of Kaur Sent: Thursday, November 10, 2016 6:43 PM To: arslist@ARSLIST.ORG Subject: Remedy 9.0.01 - CPU issue Hi All, We did an upgrade from 7.6.04 to 9.0.01. Since then we are having sporatic cpu issues. CPU utilization on the app server spikes to 80% and remedy services stops responding. Even if the cpu comes down to <20%, remedy would not respond until the services are restarted. We did several performance improvement changes on the system but nothing worked. Increased # of processors on vm, RAM, java heap size. Also changed email engine java heap size and setup a private email thread. Nothing significant in remedy server logs. Nothing seems to have worked. Please help! Does anyone have this issue too?

Re: Remedy 9.0.01 - CPU issue
I would suggest that you check if there is any thread deadlock. You can use jvisualvm ( under jdk/bin dir) or yourkit profiler ( need license). Easier will be to take just a thread dump to see where each thread is.
