Best way I've found it to keep track of the server over a period of time. nagios and mrtg are your friends here. You can use some more primitive methods, like ps ax|grep postgres|wc -l to see how many postgres backends are running. You need to figure out exactly what's happening to the machine before it dies, but as its approaching that point. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
