Thanks Tom. Where can I check the "ulimit"? Is it in the config?

I did a "ulimit -a"  (found the command through Google, on an archive
posting by in fact you! -- http://snipr.com/pg_ulimit ) and got the
following output:


~ > ulimit -a
core file size          (blocks, -c) 1000000
data seg size           (kbytes, -d) unlimited
file size               (blocks, -f) unlimited
pending signals                 (-i) 1024
max locked memory       (kbytes, -l) 32
max memory size         (kbytes, -m) unlimited
open files                      (-n) 4096
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
stack size              (kbytes, -s) 8192
cpu time               (seconds, -t) unlimited
max user processes              (-u) 14335
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited


Any idea how to configure this? That is how that thread on an archived
discussion ends too -- the poster did not seem to get any response to
his question about how to tweak this.

Many thanks!
