What messages did you get in the Postgresql logs? What other parameters have changed? From: pgsql-performance-owner@xxxxxxxxxxxxxx
[mailto:pgsql-performance-owner@xxxxxxxxxxxxxx] On Behalf Of Qiang Wang Hei: We have
PostgreSQL 8.3 running on Debian Linux server. We built an applicantion using
PHP programming language and Postgres database. There are appoximatly 150 users
using the software constantly. We had some performance degration before and
after some studies we figured out we will need to tune PostgreSQL
configurations. We have
10GB memory and we tuned PostgreSQL as follow: -
max_connection = 100 -
effective_cache_size = 5GB -
shared_buffer = 2GB -
wal_buffer = 30MB -
work_mem = 50MB However
we suffered 2 times server crashes after tunning the configuration. Does anyone
have any idea how this can happen? BR Kevin
