java.lang.OutOfMemoryError: GC overhead limit exceeded

There was no global memory shortage, so something ate up the memory inside PAU.

Cause

Memory leak in PAU daemon.

Resolution

In order to trace down similar issues, it is needed to append -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/log/pau options to the PAU init script /etc/init.d/pau at the following spot:

JAVA_MEMORY_OPTS="-Xms1303m -Xmx1303m -XX:MaxPermSize=256m"

so that it turns to:

JAVA_MEMORY_OPTS="-Xms1303m -Xmx1303m -XX:MaxPermSize=256m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/log/pau"
