Here's the output of ulimit -a by the "postgres" user the database is
running under:
[postgres@170226-db7 ~]$ ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
max nice (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 139264
max locked memory (kbytes, -l) 32
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
max rt priority (-r) 0
stack size (kbytes, -s) 10240
cpu time (seconds, -t) unlimited
max user processes (-u) 139264
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
I think this means it does not have an artificial memory limit imposed,
but is there a specific setting beyond these I could check do you think?
