Обсуждение: Dead Postmasters
On a couple of my installations, I've noticed that after a few days there are several "dead" postmasters (i.e., not associated with any running backend). When I do a ps -ax (RedHat 6.1, Postgresql 6.5.3) I see: ... [postmaster] [postmaster] [postmaster] [postmaster] [postmaster] [postmaster] ... and several /usr/bin/postgres ..... lines The problem is that there are more [postmaster] lines (sometimes 4 or 5 times as many) as there are /usr/bin/postgres lines. When I do a kill -TERM pid on all of the [postmaster] pids or restart the postmaster, the system gets much faster. The problem is I also cut of "live" connections in the process. My question is: Is there any way I can determine which of the [postmaster] entries are associated with which /usr/bin/postgres entries? Thank you! Len Morgan
What I always do is "ps -axf", which will display a "tree" of the processes : you'll know which ones are children of theothers. I don't know if the "dead" postmaster will be shown in a readable location... The problem seems to be somewhere else (kills/signalsto the postmaster/backends, not correctly disconnected connections, etc) Nicolas Huillard G.H.S Directeur Technique Tél : +33 1 43 21 16 66 Fax : +33 1 56 54 02 18 mailto:nhuillard@ghs.fr http://www.ghs.fr -----Message d'origine----- De: Len Morgan [SMTP:len-morgan@crcom.net] Date: samedi 22 avril 2000 17:02 À: pgsql-admin@postgresql.org Objet: [ADMIN] Dead Postmasters On a couple of my installations, I've noticed that after a few days there are several "dead" postmasters (i.e., not associated with any running backend).

This can be set in an environment variable in the same script that starts the postmaster. The name of the varible is in the docs. -- Anthony E.
