RE: OpenJMS crashing! Help!

Are you publishing to an administered destination
(one you look up from JNDI)?
In your initial post you mention you are using NON_PERSISTENT
delivery mode, but the latter one mentions 'persistent'. Which is it?

Looking at your parameters, try reducing the destination cache size,
maxthreads are memorycheckinterval.
