Problem with JDBCRealm in Tomcat

Hi!

I'm getting 'Connection reset by peer' and 'Socket closed' errors using
JDBCRealm in a web application running on Tomcat 4.0.3.

I am using RedHat Linux 7.3 and Java 1.4, and connecting to a PostgreSQL 7.2
back-end running remotely on RedHat Linux 7.3. It seems to work fine for a
while, but after a while (typically the next day) the error will occur.

I am using the pgjdbc2.jar JDBC driver, which seemed to be the appropriate one
for my setup. I have looked at the Java source code of this driver, and it
seems that the error occurs within a synchronized block, after the SELECT
statement has been written to the stream (it shows up in the PostgreSQL
server's log, too) and while reading - or trying to read - the response.

Anybody have any clues as to what might be wrong? All help greatly
appreciated!

Yours,
