EAP 7.1 High CPU Consumption in Production

knvlngupta Mar 23, 2018 12:05 AM

Hi,

We have upgraded the server from EAP 6 to EAP7.1 last week, but EAP 7.1 consuming CPU around 100% in production with just default configuration and also see latency issue..

Same application was working perfectly fine in EAP 6.

Can someone please suggest what needs to be done ..?

is there an issue in EAP 7.1 bcz when the app was in EAP 6 we never had CPU issue.

Take regular thread dumps (around 3 with an interval of around 5 seconds between each) when this high CPU usage occurs and attach them here. They should tell us what's going on during that time. For taking thread dumps you can use the jstack command that comes with Java runtime or any other method as explained here ThreadDump
