Resin halting due to stalled shutdown

[baoqinye]

We are using Resin 3.2.1 on Windows 2008, JDK 5. We recently experience a very weird problem. The Resin servers will restart itself almost every day. In the jvm-default.log, we saw this message:

Resin halting due to stalled shutdown

Anyone has any idea what this means? There are no other error messages. Resin is running as a Windows service so taking a heap dump or thread dump is not easy.

Thanks

Looking at the source, that message should only show up when Resin is trying to shut down, but couldn't within a specified amount a time, thereby forcing us to terminate/halt Resin. So the underlying issue is: why is Resin shutting down in the first place?

To find out what's going on, you will need to turn up com.caucho logging level to fine. I suspect there may be a GC issue.
