java.sql.SQLException, message FATAL 1: This connection has been terminated by the administrator

Hello,
We are developing an app on Apache Tomcat 4.0.2 ( apache 1.3.22, tomcat
4.0.2, jdk 1.2.2 ) running on Redhat 7.1 with postgresql 7.1.3 as the
backend.  Ever since going live with the tomcat build, we have been getting
the following errors:

 "Unable to retrieve new session ID from database; class
org.postgresql.util.PSQLException, message An I/O error has occurred while
flushing the output - java.io.IOException: Broken pipe"

&

 "Unable to  retrieve new session ID from database; java.sql.SQLException,
message FATAL 1: This connection has been terminated by the administrator."

I do not have more information at this time regarding the events that lead
up to this error, but it occurs when logging in and after logging in so I am
certain it involves different queries.

I have examined the database logs and only find messages that coincide with
the occurrence of the above errors as follows:
  DEBUG: connection: host=nnn.nnn.nnn.nnn user=xxxxx database=xxxxxx
  pq_recvbuf: recv() failed: Connection reset by peer

Restarting httpd ( which on our system restarts apache and tomcat, but not
postgresql ) clears up the problem for awhile.

Any help regarding the postgresql databases role/solution in this problem
would be greatly appreciated.
