Thread: Emergency case: Postgres problems
Dear Sir,
I will highly appreciated if anyone could inform me how to solve the following problems in Postgres.
Specifically, sometimes there are the following messages informed by postgres.
------------------------------------------------
NOTICE: Message from PostgreSQL backend:
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.
pqReadData() -- backend closed the channel unexpectedly.
This probably means the backend terminated abnormally
before or while processing the request.

The Postgres version is 7.0.0 run on Red Hat Linux 7.1 Upgrade to 7.0.3, which is the latest bugfix release of the 7.0 version. There is a good chance that the error causing your database process to dump core is fixed in it. If the problem persists after, you should look for the core file in your database directory, use gdb to get a stack backtrace and post that information to the list again.
