OutOfProcThread Exception, please help!

[Johnny Poon]

Hi,

I'm running some servlet and JPS WebShpere 3.5 on Win NT 4.0 fixpack
6. I got this error once in a while and have no idea what causes it.
It doesn't have any trace back to the code we wrote. I've searched on
this newsgroup about this problem. I saw numerious posting but no one
had an answer. Does anyone out there have any answer? Any help will
be appreciated.

This is the stack:
