IpcMemoryCreate: shmget(key=5432001, size=1441792, 03600) failed: Not enough memory

Hi all,

I am using PostgreSQL version 7.2 in WIndows 2000. The postmaster
reports
the following problem and quits when lot of data is being inserted into
the
database.

Has anybody encountered a similar problem. If so, what is the solution
to
this. Are there any patches available for this error. Should we migrate
to a
different version.

We are going live this month end and it has become a show stopper now.

Thanks to all in advance for the response.

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 1441792 bytes), reduce
PostgreSQL's shared_buffers parameter (currently 64) and/or
its max_connections parameter (currently 32).

The PostgreSQL Administrator's Guide contains more information about
shared memory configuration.
