Subject RE: log4j SEVERE ThreadDeath in Tomcat 5.0.25
Date Thu, 05 Aug 2004 13:28:13 GMT
Excellent :) I have tried everything in the bugs that relate to this issue..

http://nagoya.apache.org/bugzilla/show_bug.cgi?id=26372
http://issues.apache.org/bugzilla/show_bug.cgi?id=27371

but it's still occurring. I wish I could put together a use case for you but the error is
so sporadic. One day we can compile the whole day without a problem, the next 1 developer
gets the ThreadDeath every time he compiles and some days all developers are getting it.

i ended up creating each developer a separate tomcat development instance but each developer
is getting the problem at different times.

please let me know if I can be of further help in debugging this for you

Cheers, Allistair.
