Can someone please tell me what is going on. while querying a postgres database i am unable to access any crap from zope. I have tried creating a db connection in a enternal method and querying through that but it still locks and wont serve any requests. We saw a similar problem description recently in this list.

There, ZODBCDA was blocking during database queries. Maybe, your database adapter has similar problems. Dieter
