Out Of Memory Error

[murali mohan <mu...@gmail.com>]

I have now several builds running in Continuum. In one of the builds, i can
see an Out of Memory Error in the logs. The stack trace is given below:

Where should I increase the heap size -
1) In the JAVA_OPTS which is the JVM arguments for the tomcat which runs
continuum
or
2) MAVEN_OPTS which is the JVM arguments for Maven operations.

Murali.
