Обсуждение: postgres 8.1 crashing
my previous post just vanished... Hi! I just upgraded pg 8.0.3 to 8.1 (dump and reload) and outcome was a corrupted database. pg 8.1 seemed to fly but backends were crashing :-/ While tailing the log file I noticed a couple of: ERROR: invalid memory alloc request size 1101389186 Hardware is Sun v40z with 64bit Debian Sarge, Linux 2.6.13.2. Size of database is somewhere around 500M rows and it's loaded by a website with a lot of traffic. Configuration: http://tuner.bdb.fi/postgresql.conf Some backtraces (update queries are included in the bt): http://tuner.bdb.fi/pg_crashing.txt http://tuner.bdb.fi/pg_crashing2.txt http://tuner.bdb.fi/pg_crashing3.txt And users-table which is involved in all the crashes is described here (contains ~700000 rows): http://tuner.bdb.fi/pg_crashing_table.txt I tried to reindex the table but it didn't help. PG went corrupted after a while: http://tuner.bdb.fi/pg_crashing4.txt Any ideas? |\__/| ( oo ) Kari Lavikka - tuner@bdb.fi - (050) 380 3808 __ooO( )Ooo_______ _____ ___ _ _ _ _ _ _ _ ""
