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.

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.

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.
