Re: Serious Crash last Friday

Hello all,

unfortunately I didn't get a really helping answer from the list yet.

Additionally yesterday night there was again a problem with some SELECTs:

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.
DB-Error in /web/intern.city-map.de/www/vertrieb/wiedervorlage.pl Code 7:
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.

Command was:
SELECT name
FROM regionen
WHERE region='0119';
at /web/pm/CityMap/Abfragen.pm line 135

This is really annoying.

When I noticed it this morning, I dropped all indexes and recreated them.
Then I ran a VACUUM FULL VERBOSE ANALYZE - afterwards the same query worked
properly again.

I have now created a cronjob that will drop and recreate all indexes on a
daily basis.
But shouldn't this be unnecessary ?

Mit freundlichem Gruß
