Thread: Failed system call was shmget(key=1, size=1155072, 03600).

Failed system call was shmget(key=1, size=1155072, 03600).

Hi,
when building postgreSQL 8 I get the following error message:

DETAIL:  Failed system call was shmget(key=1, size=1155072, 03600).
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 1155072 bytes), reduce PostgreSQL's 
shared_buffers parameter (currently 50) and/or its max_connections 
parameter (currently 10)

What is the best way to resolve this? max_connections = 10? Does that 
figure auto increase as more users request data?

regards

Andrew

This has been addressed many times, and for many OS's
(*Linux, *BSD, etc...).

What are you trying to run this on?  It might be that you need to
alter your kernel settings.
