[pgpool-general: 4533] Unable to connect to PgPool virtual IP.

[Avi Weinberg]

Hi all



Today I was unable to connect to pgpool virtual IP and port 9999 (version 3.5).  I checked the running processes and got the following:



[root at pgpool pgpool-II-95]# ps -ef | grep pool
root      5561  9837  0 Mar08 pts/1    00:00:16 pgpool -n -d -a pool_hba.conf
root      5562  5561  0 Mar08 pts/1    00:00:08 pgpool: watchdog
root      5563  5561  0 Mar08 pts/1    00:00:02 pgpool: lifecheck
root      5567  5563  0 Mar08 pts/1    00:00:04 pgpool: heartbeat receiver
root      5569  5563  0 Mar08 pts/1    00:00:05 pgpool: heartbeat sender
root     12688  5561  0 10:31 pts/1    00:00:00 pgpool: PCP: wait for connection request
root     12689  5561  0 10:31 pts/1    00:00:03 pgpool: worker process



After pgpool restart I got a much larger list and I was able to connect.  What might have caused the above situation that required me to reset pgpool?



Thanks!
