Lockup fetching from database

I'm running PostgreSQL 8.1 on OS X Server 10.4.3 using postgresql-8.1-404.jdbc3.jar and I'm experiencing some lockups when querying from the database through our java WebObjects program.

Here is a dump of the thread where the problem occurs:

So it seems that it's locking up retrieving data from the database. Is there a timeout parameter or something that can be set so if it takes too long to retrieve from the database I can handle an exception and continue on with my program? Right now all the other threads in my application start to block waiting for this one to complete and eventually my entire application instance locks up.

Thanks,
