Hi,
Tomcat 4.1.12
OS: W2K
JRE: Sun 1.4.1_01 (Originally found using 1.4.0)
I am seeing a problem with Tomcat closing a socket connection and having a
write error. This happens with both SSL and regular sockets (the log example
that is at the end show an SSL example.) I can reproduce the problem at
times but sometimes that test case works (and the page renders as it
should.) Our website sits on top of a data warehouse and I mostly experience
the problem with the pages that have the longer queries.
Does anybody know why this happens? Is there a fix? What can I do to try
figure out what is causing the problem? I have turned up the debugging level
on Tomcat (to 1) and that didn't produce much more information. I have added
(println) statements to my code to see if there is a problem in it. It
appears that my code always completes even when the socket connection is
broken.
Basically, I am at a point where I don't know what to try next.
Here is the log output:
