reboot multiple times a day

[goblin]

hello all,
i am running two RPI with domoticz but one is rebooting multiple times a day and can't figure out why.
i have found something on Domoticz troubleshooting about crashlog / signal handling.
Below a snapshot of the lines around the signal_handler.

Thread 2 (Thread 0x6d8ff200 (LWP 4287)):
#0 __waitpid (options=0, stat_loc=0x6d8fde18, pid=4288) at ../sysdeps/unix/sysv/linux/waitpid.c:30

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

domoticz works most of the time but a lot of functions are not e.g. (any timer related switch) turn of after 5 minutes.

help would be very appreciated

good evening,
i think i have found it.
i am using "Monit Service Manager"
it is running for 10 hours after stopping the monitor.
next challenge is to figure out why.

regards

There normally is an monit log where you can see the actions it has taken.
