Subject Service killed by signal 9
Date Fri, 10 Nov 2017 09:31:00 GMT
Since switching to jsvc, randomly I am getting tomcat restarting, looking
at the logs I see that the jsvc is using alot of memory total-vm:  and
being killed by the system.

Nov  9 13:11:11 prodbox kernel: Out of memory: Kill process 1287 (jsvc)
score 121 or sacrifice child
Nov  9 13:11:11 prodbox kernel: Killed process 1287 (jsvc)
total-vm:3453120kB, anon-rss:378280kB, file-rss:0kB, shmem-rss:0kB

I am using the below on properties on the startup (from previous version
statup scripts):

-Xms256M -Xmx768m -Xss1280k -XX:+UseParallelGC -XX:MaxGCPauseMillis=1500
-XX:GCTimeRatio=9 -server -XX:+DisableExplicitGC

(I replaced -Xss256k with -Xss1280k to stop crashing see

Is there a way to limit the total-vm or find out why its got so big?
-XX:+DisableExplicitGC ??

Standard tomcat install with apache/modjk.
Cheers Greg
