All,
While running a Select query we get the below error:
ERROR: out of memory
DETAIL: Failed on request of size 192.
Postgres Conf details:
shared_buffers = 256000
work_mem =150000
max_stack_depth = 16384
max_fsm_pages = 400000
version: 8.1.3
We are using 8gb of Primary memory for the server which is used as a
dedicated database machine.
The data log shows the below message after getting the Out of memory
error. Also attached the explain for the query. Can someone let us
know , if have some worng parameter setup or any solution to the
problem?
Regards,
Nimesh.
Hi Nimesh,
I'd try decreasing work_mem (try something smaller like 16384 and work
up if you'd like), since you have lots of hashes being built for this
query, you may simply be running into a limit on process size
depending on your platform. Also look at "ulimit -a" as the postgres
user to make sure you aren't running into any administrative limits.
Cheers,
Rusty
