HANDLER THREAD PROBLEM

[Arun Chhatpar <Ar...@nbci.com>]

Hi team,
	I am running latest Tomcat build with JDK1.2.2 (Hotspot), Apache on
Solaris 5.6 . And I see this error most often on the console :-

HANDLER THREAD PROBLEM: java.lang.NullPointerException

And after some time, the server hangs. I am not sure what is causing Tomcat
to die. Some body on this list suggested to compile the latest jserv_mod.so
to eliminate this problem. But that didn't help. 

I would highly appreciate any suggestions or comments. 

Thanks,
Arun.

For the record, I'm getting the same error, 1.2.2 linux.  For me it
seems to be triggered only when the response exceeds a certain
(BUFSIZ?) size.
