Hello List,

I am having some difficulty with heath check in pgpool. It appears that it can not make a persistent connection so it fails health check.

The servers are listed as up
prod1.db.power-soft.net5433Up[Detail]

Dec  4 11:49:47 pgpool1 pgpool[67018]: make_persistent_db_connection: connection to prod1.db.power-soft.net<http://prod1.db.power-soft.net>(5433) failed
Dec  4 11:49:47 pgpool1 pgpool[67018]: health check failed. 0 th host prod1.db.power-soft.net<http://prod1.db.power-soft.net> at port 5433 is down
Dec  4 11:49:56 pgpool1 pgpool[67030]: check_replication_time_lag: could not connect to DB node 0, check sr_check_user and sr_check_password

I am using postgres/postgres for health_check_user/password which I can connect with manually to both the databases.
sr_check_user/password are using postgres/postgres as well.


Any suggestions out there?  The only thing I can find in the FAQ that is related to this is if the user does not exist that its trying to connect with and the return error is completely different.

Both databases are postgresql 9.0.10

pgpool is on a separate machine pgpool1.db.power-soft.net<http://pgpool1.db.power-soft.net>  there is no firewall blocking connections...

If I enable failover it will make both prod1 and 2 down.

here is the debug from a restart, if this helps any


Any help would be greatly appreciated!



pgpool restart succeed
