Обсуждение: pgstat wait timeout

Hello

One of our production servers log files is being flooded with the message:

2012-03-26 00:00:11 BRT AVISO:  pgstat wait timeout
2012-03-26 00:00:19 BRT AVISO:  pgstat wait timeout
2012-03-26 00:00:31 BRT AVISO:  pgstat wait timeout
2012-03-26 00:00:39 BRT AVISO:  pgstat wait timeout
2012-03-26 00:00:51 BRT AVISO:  pgstat wait timeout
2012-03-26 00:00:59 BRT AVISO:  pgstat wait timeout
2012-03-26 00:01:11 BRT AVISO:  pgstat wait timeout

(actual log snippet)

This instance is running under a Windows Server 2008 R2 Standard,
Postgres version is 9.0.5 (64 bits).

Do you have any ideas of what is the cause of this?

Best regards

Norberto
