Hi,
first up Happy New Year to everyone :-)
Secondly, I've been trying to stabilize my Xwiki install on FreeBSD 8.2
x64. My machine is a quad core box with 4GB RAM and not much usage in
terms of people viewing the wiki etc....
I am getting this error:
umbers=0&rev=11.1" java.lang.OutOfMemoryError: Java heap space
Exception in thread "http-8180-Acceptor-0" java.lang.OutOfMemoryError:
Java heap space
I have attempted a resolution by including: - after Google'ing heavily
to see what could be done to rectify the issue.
JAVA_OPTS=-Xmx1024m
JAVA_OPTS=-Xms1024m
#JAVA_OPTS=-XX:PermSize=64M
#JAVA_OPTS=-XX:MaxPermSize=256m
at the top of the catalina.sh file but as I've just found out it didn't
work.
The strange thing is that I had this wiki migrated to an old PowerMac G4
733MHz with 384MB RAM and even though the cpu went up to max due to the
amount of swap space consumed the system still worked fine for longer
then my BSD machine at least.
Can anyone give me a hand in order to diagnose the problem?
I have tried this also on Nexenta Core 3 (OpenSolaris) on a virtual
machine running on my notebook with 2GB RAM dedicated to it which worked
fine also and was up for many weeks even though pathetically slow.....
actually I was running Glassfishv3 but it was still Java!
Thanks,
Indeed, the proper fix is to increase the amount of memory that the JVM
can use, and it should be done with the -Xmx1024m parameter as you
tried. And that value should be enough. Seeing that it doesn't work,
then catalina.sh must somehow discard that JAVA_OPTS variable along the
way. To test it, just do a ps or top after Tomcat is started to see
exactly what command line is being executed; does it have your Xmx
setting or not?
Anyway, I don't know how FreeBSD packages Tomcat, but normally you
shouldn't edit catalina.sh directly, there should be a dedicated
configuration file where you can specify parameters. On my Gentoo it's
in /etc/conf.d/tomcat-6. And the recommended variable to set is
CATALINA_OPTS, not JAVA_OPTS, and catalina.sh should append whatever you
set in CATALINA_OPTS to the final JAVA_OPTS that it computes and which
gets passed to the java command.
