Clock stops working/stack several times a day

[michlb1003]

Hi

Hello
i’ve got a problem…
more than once a day the clock quits working… sometimes after a few hours pm2 restarts automatically and the clock works again for a while…

Platform [ Raspberry Pi 3]: with the latest jessie-updates, uses just for magicMirror and as OpenVPN gateway (using pivpn)

Magicmirror Modules:
*clock (analog and digital)
*calendar
*weather & weather forecast
*compliment
*rss

monitor-switch off is via pir and python solved…

can anyone help me please, or does anyone have any idea?
