Hi all,
as the log says tomcat is out of perm gen space, if You want to know
what or where it is going just add parameters like Jorge said:
export JAVA_OPTS='-Xmx756m -server -XX:MaxPermSize=256m'
but also add -XX:+PrintGCDetails
export JAVA_OPTS='-Xmx756m -server -XX:MaxPermSize=256m -XX:+PrintGCDetails'
and simply watch the output.
In the mean time read about the java memory management.

Best greetings,
Paweł Wielgus.
