message from backend

Hello,

I am getting the following message intermittently. I am running v7.02
as the database for an Apache/PHP4 application. Can anyone point me
in the right direction as to troubleshooting this type of problem?

The Postmaster has informed me that some other backend died
abnormally and possibly corrupted shared memory.
I have rolled back the current transaction and am going to terminate
your database system connection and exit.
Please reconnect to the database system and repeat your query.
