[HACKERS] HS/SR Assert server crash
I was able to easily crash the standby server today just by starting it and connecting to it via psql. The master was idle. The failure was: LOG: streaming replication successfully connected to primary TRAP: FailedAssertion(!(((xmax) = ((TransactionId) 3))), File: procarray.c, Line: 1211) LOG: server process (PID 12761) was terminated by signal 6: Abort trap LOG: terminating any other active server processes My master postgresql.conf was: wal_level = hot_standby # minimal, archive, or hot_standby archive_mode = on # allows archiving to be done archive_command = 'cp -i %p /u/pg/archive/%f /dev/null ' # command to use to archive a logfile segment max_wal_senders = 1 # max number of walsender processes My slave postgresql.conf was: port = 5433 # (change requires restart) wal_level = hot_standby # minimal, archive, or hot_standby archive_mode = off # allows archiving to be done archive_command = 'cp -i %p /u/pg/archive/%f /dev/null ' # command to use to archive a logfile segment hot_standby = on# allows queries during recovery max_wal_senders = 1 # max number of walsender processes and my slave recovery.conf was: restore_command = 'cp /u/pg/archive/%f %p' # e.g. 'cp /mnt/server/archivedir/%f %p' standby_mode = 'on' primary_conninfo = 'host=localhost port=5432' # e.g. 'host=localhost port=5432' Let me know what additional information I can supply. -- Bruce Momjian br...@momjian.ushttp://momjian.us EnterpriseDB http://enterprisedb.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
