I asked in the dev email list without a response.
So will also here.
I have observed a case when Kamaili debug module try to grab the lock on shutdown and not able to do it.
As a result, the Kamailio process is stuck and not able to restart (dead lock).
To resolve such a case I want to utilize systemd watchdog feature
To use this feature I need to send sd_notify(3) with a message string of "WATCHDOG=1" from the main process.
Link
According to systemd doc watchdog can be applied only to one process. Link
If the $WATCHDOG_USEC environment variable is set, and the $WATCHDOG_PID variable is unset or set to the PID of the current process, the service manager expects notifications from this process.
Could you suggest how to embed this systemd call to the main process? This will allow use systemsd watchdog
feature.
