Hi Raul,

I've seen error messages like this several times when my servers were
under heavy load or when the JVM locked itself somehow. In either case
it hasn't been related to freetds_jdbc at all.

I've seen reports of errors like yours on the JServ User's list. In
many cases they were due to exhausted resources (are you sure you're
closing all connections?).

And finally you could be triggering a deadlock - maybe inside
freetds_jdbc, maybe in your code as timings changed when you switched
to it.

Do you think you can get a thread and monitor dump from the JVM in a
situation like this? I'm Unix guy and don't know how to do this on
Windows but on Unix you would send a QUIT signal to the process.
