That's good. Is that a public web site?

That could happen if you close a statement twice. If that is the case
then the only consequence is a WARN log event, but I guess it would be a
good idea not to close it twice. Is it possible that is the problem?

That message appears during shutdown. We need to make it a less alarming
debug message.

But this line suggests to me (quite strongly) that the JVM is shutting
down. The only way that I can think of for the ShutdownHook.run method
to be called is by the JVM.

What JVM are you using? Do you have any other evidence that might
suggest this is happening?

Do you see log events for Proxool restarting after this shutdown
activity?
