JDBC driver

Hi List

I'm running Jakarta tomcat 4.0 on a RedHat 7.1 and I'm using a
Postgresql database.
The system had been running for two weeks without problems but then i
got an exception from tomcat.
This is the exception i got:

2001-11-08 14:23:04,607 ERROR UserDBHandler - Problem executing query
2001-11-08 14:23:04,607 ERROR UserDBHandler - An I/O error has occured
while flushing the output - Exception: java.io.IOException: Broken pipe

I had to restart tomcat to make it work again.

I could connect to other parts of the database without problems.
I tried to look in the postgres log but no messages were generated wich
tells me that the connection was never made.

Any ideas?
