Hi, We have a front-end server taking care of Nginx, memcached and Postgresql. Last night the postgres daemon crashed (traffic was very low at that time) with the following error: 2010-12-20 03:34:30 EST DETAIL: Failed system call was shmget(key=5432001, size=1124474880, 03600). 2010-12-20 03:34:30 EST HINT: This error usually means that PostgreSQL's request for a shared memory segment exceeded available memory or swap space. To reduce the request size (currently 1124474880 bytes), reduce PostgreSQL's shared_buffers parameter (currently 131072) and/or its max_connections parameter (currently 963).
For me this looks like you have shared_buffers at the default value of 128kb eg. 131072 Byte which would be way to low for 963 connections...
Not sure if this is a reason to crash. Regards Andreas
