[Supervisor-users] Setting the ulimit for stack size

[Mark Fleishman]

Hello,

I am trying to setup supervisor to start a program where the ulimit stack
size is unlimited. We have only two users on the system one is root and
the other is our application user. Both have the ulimit -s set to
unlimited for their user environment. We start our python application
using the "command =" in the supervisor ini but it does not start with the
unlimited value but with 8192. We have gotten around this by adding to the
start of the command with:

bash -c 'ulimit -s unlimited; exec python......

Now we are adding to the command with another script and would like to take
out the setting of the ulimit. How can we have the ulimit set or assumed
when starting to have the stack size set to unlimited? I have tried the
user= option and we have the environment=User="username" also set neither
seems to work. The limits conf file is also set in /etc/security/limits
for stack size to be unlimited.

For example, as a test I used a small script the outputs the ulimits -a to
a log file and the output is:

core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 1747
max locked memory (kbytes, -l) 64
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) 1747
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited

but when I login as that user from the command line I get:

$ ulimit -a
core file size (blocks, -c) unlimited
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 1747
max locked memory (kbytes, -l) unlimited
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) unlimited
cpu time (seconds, -t) unlimited
max user processes (-u) 1747
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited

Thank you for your assistance.
