I suspect it is more of a JVM-related issue.
Tomcat's failure to shutdown under some conditions
has been an intermittent discussion on this group
for several months now. It happens to me on HPUX,
but works fine on the solaris machine I have access to.
Have you tried running the shutdown command
several times? Tomcat always shuts down for me
on the third run of the shutdown script.
-- Tomcat Developers, any comments on this????
I even connected the jdb debugger to tomcat, and
did some thread dumps; my results are appended
to the end of this email.
Incidentally, I am surprised to see *any* threads
in running state, because there were *no* active
users at the time the shutdown was run (it's a
development install).
It's not a fatal problem, but it would be nice
if someone could look into it. I'll eventually
get around to it myself if everyone waits
long enough, but with my current schedule
that could be a while :-)
Cheers,
Simon
