Weird system lockups occuring when JDBC throws error

Hi all,

I’m having some problems with my postgres  installation on debian (Virtual PC 2007)

Debian etch 4.0 (running 2.6.18)

psql (PostgreSQL) 8.1.8

contains support for command-line editing

Sometimes when the driver throws an exception, it seems to lock up the whole machine. I run top on the console, and it stops. I have to reset it.

The problem is non deterministic, it seems to take a few errors before it goes down.

Previously, I was running Debian 3.1 (sarge) with postgres 7.4 (also Virtual PC 2007)  and I did not have these problems at all.

How can I start to get to the bottom of this?

Thanks,

Jay
