[midPoint] Running out of Java Heap Space

Wed Aug 24 23:01:33 CEST 2016

Is there any further recommendations for setting the Java memory
requirements?  My JAVA_OPTS is set to this.

JAVA_OPTS="$JAVA_OPTS $JSSE_OPTS -Dmidpoint.home=/opt/midpoint
-Djavax.net.ssl.trustStore=/opt/midpoint/keystore.jceks
-Djavax.net.ssl.trustStoreType=jceks -XX:MaxPermSize=1024m -Xss1m -Xmx1024m"

I'm running into the error below after an LDAP import task suspends due to
an error.  I have yet to resolve the error, see my earlier post about how
to ignore an LDAP attribute on import.  I've got plenty of memory on the
VM, but I may need to tune my Java even further.

Thanks,
Matt
