I've been looking at this one some more.
One unusual aspect is that I see the problem when running Tomcat 6 as
a Windows service, but not see it when I run the Tomcat from the
command line, using the "startup.bat" and "shutdown.bat" in the "bin"
directory.
Will, can you please try running the Tomcat 6 from the command line,
and see if the problem still happens?
This difference in behaviours leads me to believe that the problem
perhaps relates to some difference between JDKs and JREs, with the
command line using the former and the Windows service using the
latter.
Thinking that it may be memory related, I increased the memory
allocation for the Windows service to a large amount, 1024M. But the
problem still happens.
The traceback reported is attached.
At this stage, I don't know what is causing this problem, and am open
to suggestions for avenues of research to follow up.
Regards,
Alan.
