I read somewhere on the web site you are interested in seeing the errors around
OutOfMemoryError: Java heap space, so I thought I would send you this one. I
have a work around (I bounce the sun service), so this is more FYI. Hope this helps.

Hudson v1.203 is running as a service on Solaris 10. I have Windows 2003 Server
slaves and Fedora 8 slaves.

Below is the Hudson log. ** Below that is a Java heap space error from a build
prior to Hudson going down.
