When there's a problem, I'm seeing this. Notice that it took 51
minutes (!!!) before it decided to restart. The only difference
from above is that it says, "closing with 1 active requests".
Can you get a thread dump to see why that request is hung?
I can try. I haven't had any luck so far as it seems to happen
randomly.
Ok. If another 51 minute freeze happens, there should be enough time
to get a thread dump.
The <shutdown-wait-max> tag in <cluster> should determine the
maximum time Resin will wait for requests before forcing a shutdown.
I didn't configure that parameter, but the docs say the default is
60s <http://caucho.com/resin-3.1/doc/cluster-tags.xtp>. So it must
not be working, or the hang happens after that portion of the code
that forces the shutdown.
Hmm. It is 60s. The exit code uses Runtime.getRuntime().halt(1) in
that situation to force the shutdown. I don't see how the exit thread
could get trapped, though. It's designed to work even if the rest of
the system is locked up.

Here's a second instance from a different server with the same
configuration. This time the restart took 13 minutes. Again, it is
closing with active requests (3 this time), along with a message
about sessions.
