[JDEV] Jserver Core Dump - redhat 5.2

6.2 should work better.

We haven't done a lot to pin down system and memory requirements for a
Jabber server.  Obviously, the more the merrier.  I've run Jabber servers in
the past on P200s with 32 Mb and they've worked.  Our current development
boxes are a lot more powerful than that though.
