Hi Kevin, No, it is not SE-Linux and no anti-virus programs are running. I can again cross-check whether any firewall is enabled. But again if postgresql service can start without any issues, why not stats collector process the same way? Does stats collector process need any other special resource/privilege/operations/port to start? Can you let me know in this aspect, so that it would be helpful to troubleshoot better. -----Original Message----- From: Kevin Grittner [mailto:Kevin.Grittner@xxxxxxxxxxxx] Sent: Friday, April 09, 2010 7:36 PM To: 'Tom Lane'; gnanam@xxxxxxxxxx Cc: pgsql-admin@xxxxxxxxxxxxxx Subject: Re: Statistics Collector not collecting server activities "Gnanakumar" <gnanam@xxxxxxxxxx> wrote: > As you said, I notice the following in postmaster log: > 2010-04-08 17:30:41 ISTLOG: could not receive test message on > socket for statistics collector: Connection refused > 2010-04-08 17:30:41 ISTLOG: disabling statistics collector for > lack of working socket > > What is going wrong? I couldn't understand from the above lines. Is an OS firewall or anti-virus program running on this machine? Any other unusual security features, like SE-Linux? -Kevin -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
