[SR-Users] app_python3 crash woes

[Alex Balashov]

Hi,

Some exceptions generated in Python script cause a harmless traceback in the logs, while others cause Kamailio to crash:

Sep 22 06:28:34 proxy /usr/sbin/kamailio[3984]: CRITICAL: <core> [core/pass_fd.c:277]: receive_fd(): EOF on 11
Sep 22 06:28:34 proxy /usr/sbin/kamailio[3957]: ALERT: <core> [main.c:783]: handle_sigs(): child process 3965 exited by a signal 11
Sep 22 06:28:34 proxy /usr/sbin/kamailio[3957]: ALERT: <core> [main.c:786]: handle_sigs(): core was generated

Is there a reasonable way to try to prevent this type of mid-air explosion?
