[pgpool-general: 3612] Fwd: Strange error

[Mephysto]

Hi there,
I have two pgpool instance working together with watchdog and everything
seems to work with no problems.

But in log file of one of the instance I found an error that occur
continuously:


2015-04-09 22:48:42: pid 5330: ERROR:  Failed to check replication time lag
2015-04-09 22:48:42: pid 5330: DETAIL:  Query to node (2) returned no data
2015-04-09 22:48:42: pid 5330: CONTEXT:  while checking replication time lag




>From what this message can depend?

Thanks in advance.

Cheers.
