Tomcat high CPU issue

[#1]

Hi,

We are on BO 4.2 SP2. We have recently upgraded and since then we are experiencing and issue with Tomcat8.

Tomcat keeps reserving more and more memory (at least from we can see in windows Task Manager). Every other day it reaches around 2GB of memory and then it starts paging. CPU goes over the roof and we can´t even restart Tomcat, we need to kill it and start it instead.

We have modified the Tomcat settings Xmx and Xms to 4096 and restarted Tomcat but it seems that it can´t go beyond 2GB. We are on a windows server 2012 R2 64bits with 32GB of RAM available.

Has anyone encountered this scenario that can give us any clue?

Many thanks,

Sergio
