Buffer Overflow

I'm seeing this in my catalina.out log file.  I've been able to narrow 
the problem to a single JSP page, and the problem only happens with a 
single user when that user is using Windows XP/FireFox 3.6.12.   I've 
tested the page with XP/Firefox 3.6.3 and can't reproduce the issue.   
The JSP page reads and writes custom cookies.

Any ideas on what might be happening, or on how to get more information 
(like what is actually in the header)?

My apologies, I saw the word common in the log and thought it was commons.

That suggests that this is an Apache Tomcat question. You want the
Apache Tomcat users list. This is the Apache Commons users list.
