### Description We are observing shared memory leak in Kamailio. To debug this i tried to run Kamailio with valgrind using following command.

``` /usr/bin/valgrind.bin --tool=memcheck --error-limit=no --show-leak-kinds=all --verbose --track-origins=yes --log-file=vg.log --leak-check=full --leak-resolution=high --show-reachable=yes -v /usr/sbin/kamailio -P /var/run/kamailio/kamailio.pid -f /etc/kamailio/kamailio.cfg -m 4096 -M 512 ```

But, Kamailio is not able to come up. Its throwing following error: ``` CRITICAL: <core> [main.c:1643]: main_loop(): Cannot fork INFO: <core> [main.c:836]: sig_usr(): signal 15 received ```

### Troubleshooting

#### Reproduction

Can be reproduced using above valgrind command.
