In some situations a OOM dump contains valuable information. By default this feature is not enabled. If you are experiencing problems and run into Out Of Memory Errors, please enable this function.
Note: a dump is as big as the memory of the virtual java machine. So make sure that you save them to a place where enough free storage space is available (for more than one dump).
change the file /opt/open-xchange/etc/groupware/ox-scriptconf.sh like this:
# This properties sets the java options given to the groupware on start
JAVA_XTRAOPTS="-Xmx512m -XX:+UseConcMarkSweepGC -XX:MaxPermSize=128M -Dsun.net.inetaddr.ttl=3600 -Dnetworkaddress.cache.ttl=3600 -Dnetworkaddress.cache.negative.ttl=10"
to
# This properties sets the java options given to the groupware on start
JAVA_XTRAOPTS="-Xmx512m -XX:+UseConcMarkSweepGC -XX:MaxPermSize=128M -Dsun.net.inetaddr.ttl=3600 -Dnetworkaddress.cache.ttl=3600 -Dnetworkaddress.cache.negative.ttl=10 -XX:-HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/<path>/java_pid<pid>.hprof"
adjust <path> to your settings.
