Subject: Postgresql 7.0 JDBC exceptions - broken connections ?

Hello,
As I told you in an former mail I'm trying to migrate an application to use
PostgreSQL 7.0. The application now seems to be working pretty well and I
have 5 users that have been testing our web application with the PostgreSQL
database for the past 24 hours.
The application runs with a connection pool, but after some time some of
these connections seems to be broken. Ie. only some of the queries work - I
will change the connection pool code to handle this, but I would like to
know if anybody know why the connections gets into an unusable state. Could
it be back crashes or similar things ? I'm turning on debugging for the
database server to see if can find anything there, but anyway here is the
exception I get :
select distinct entity.*,location.loc_id,location.loc_name
from entity,locationmap,location,entityindex2 as e0
where locationmap.ent_id=entity.ent_id and locationmap.loc_id=location.loc_id and e0.ei_word='kjøttbørsen' and e0.ent_id=entity.ent_id and ENT_STATUS=4
order by ent_title,location.loc_name,location.loc_id
