Summary

0003527: Resin fails to restart in a timely fashion (perhaps because of active requests?)

Description

Environment: Resin Pro 3.1.9, Windows 2003 Server 64-bit, Java 1.5_18 64-bit.

I'm seeing a bad problem with Resin "waiting" many minutes before it restarts. I haven't been able to get a thread dump or sample because it happens intermittently. But I am seeing something in the logs that might point in the right direction.

I don't know if this is a bug or something that can be fixed with a configuration change. Nevertheless, I have filed a bug.

This is happening in our development environment, which obviously gets very little traffic. We're planning on upgrading to Resin Pro 3.1.x in our production environment within the next couple of weeks, but obviously this is a big show-stopper for us.

Note: Our restart process is to use the windows "sc stop \\machine resin", followed by a series of "sc query \\machine resin" to make sure it has stopped, followed by an "sc start \\machine resin". With Resin Pro 3.0.21, this process worked flawlessly. It's only with Resin Pro 3.1.9 that we started having this problem.

What I usually see in the log files during a normal restart sequence is something like this. Notice the time stamps. Everything happens pretty quickly.

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".

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.

Any ideas?
