[Pgpool-general] Understanding Error Messages

[Jay Payne]

We are running a two node pgpool-II database set and are using Master -
Master replication.

What do these errors mean?

Dec 30 15:46:17 pgpool1-2 pgpool: 2008-12-30 15:46:17 LOG:   pid 3188:
ProcessFrontendResponse: failed to read kind from frontend. frontend
abnormally exited
Dec 30 15:46:17 pgpool1-2 pgpool: 2008-12-30 15:46:17 ERROR: pid 3188:
pool_process_query: 1 th kind E does not match with master connection kind S

Dec 30 15:46:21 pgpool1-2 pgpool: 2008-12-30 15:46:21 ERROR: pid 4413:
pool_process_query: 1 th kind E does not match with master connection kind C
Dec 30 15:46:21 pgpool1-2 pgpool: 2008-12-30 15:46:21 LOG:   pid 4413:
do_child: exits with status 1 due to error

It would be nice if pgpool would log the query that generated the error.


There is no way we can run pgpool in debug mode in production.

Is there a document that explains what kind E or kind S means?

Thanks in advance for your time.
