The database only holds a single shared memory segment, which doesn't seem to have a relevant size. Seems the same to me, so I will disregard that. > I am surprised to see this since I would have expected much more shared memory to be used by the database. Is there anything in the configuration that prevents the shared memory from being used? I am not too current with postgres, that one was a thing which happened to me when I did more administration, and is one you always want to check. I assume you have all checked, but I would follow by insuring every mounted partition in your system has space. I am not current on the details, but I know Pg can be mmaping things and doing other stuff. Your problem seems more of resource exhaustion, so I would follow by checking that, both disk, tmpfs and all the other stuff. I cannot give you advice on that as it depends a lot on your server configuration and from the age in the mssages I suspect you have the usual suspects debugged. But as you have a configuration crahsing in minutes and it seems to be a dev server you could do it easily. Sorry. Francisco Olarte.
