#400: Postgres error (apparently won't start) ------------------------------------+--------------------------------------- Reporter: mrzombie@… | Owner: wsanchez@… Type: Defect | Status: new Priority: 5: Not set | Milestone: Component: Calendar Server | Severity: Other Keywords: | ------------------------------------+--------------------------------------- Comment(by dre@…): Replying to [comment:1 dre@…]:
It seems this was due to Mr. Zombie having a separate instance of postgres running. When he terminated that instance, calendar server was able to start its own postgres instance. This requires investigation...
Have a look at CalendarServer/CalendarServer/data/Logs/postgres.log. This hopefully will contain some information about why calendar server's postgres instance failed to start. I've got a dollar that says it's kernel shared memory limits. If this is true, what you encountered is not a bug, but rather a configuration issue, and you can read more about the tunings you would need to run multiple instances here: http://www.postgresql.org/docs/8.1/static/kernel-resources.html. Also note that although there is a postgres.conf config file, a couple key settings are specified as command line options when calendar server starts postgres. They are: -c shared_buffers=30 -c max_connections=20. I mention this only because the command line args always take precedence over what's in the config file. -- Ticket URL: <http://trac.calendarserver.org/ticket/400#comment:2> Calendar and Contacts Server </> HTTP/WebDAV/CalDAV Server
