I am using postgres 8.4.1 & pgpool 2.3.3 with:
replication_mode = true
load_balance_mode = true
replicate_select = false
reset_query_list = 'ABORT; DISCARD ALL'
master_slave_mode = false
parallel_mode = false
Twice in the last 4 weeks, pgpool has hung (port 9999) for no apparent
reason. The ps command shows a small number of connections. The top command
shows plenty of memory and cpu available. I can access postgres fine (port
2345) on both primary and secondary. The pgpool log contains no error
messages, but there are no recent messages at all. So, it seems that pgpool
stopped writing to its log at the same time it hung. The postgres logs are
normal.
Has anyone had any similar experiences? Can anyone suggest where to look for
possible causes and/or solutions?
Thanks,
Lou ...
