I'm answering my own question because I've solved it.
It seems to be related the the JVM settings I've been struggling with.
As said before I'm a Windows user learning Ubuntu and sometimes simple
tasks are very complicated for me ;)
I had created the setenv.sh file in the wrong location, making Tomcat not
using it.
I know created the file in /usr/share/tomcat7/bin/
And the content is:
-server -Xms512m -Xmx1024m
-XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=256m
-XX:MaxPermSize=256m -XX:+DisableExplicitGC -XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=36000
-XX:+UseParallelOldGC -XX:+UseParallelGC
-XX:NewRatio=2 -XX:+AggressiveOpt
After restarting Tomcat GWC is now continuing pre-seeding my files.
I'm still looking for some explanation about the used sizes in setenv.sh.
I have a 2GB server. What is the relation between for example -Xmx and the
available RAM?
Thanks,
Paul
