The memory size allowed to your server is apparently insufficient;
or there could be a memory leak (though no APAR in the APAR database).
Check your Unix Limits values under which the server is being
started, and consider making them Unlimited if not already, or do
whatever can be done under your HP operating system to boost the
memory that your server is allowed, and restart it.
Perhaps someone else with an HP server has more perspective on this.
