Hello,
My Raspberry Pi with openhabian is connected to internet via USB GSM modem. Recently my modem disconnects from the internet from unknown reason at around 00:30 AM and then connects back online at around 06:00 AM. To my horror the syslog file is around 250 MB big in size and contains millions lines containing this string: "dhcpcd[365]: received SIGPIPE". Few hundreds these lines per one second. I suspect some issue with scripts related to my modem. What could be the problem?

Additional info:
In syslog there is sometime also this segment of lines repeating in a loop:

Code:

I have disabled "comitup-web.service". Will se if it helps and if it does not break the system.

So it did not help. After 00:30 AM it still disconnects from internet and getting these logs bellow.
Is there a way to disable "dhcpcd" service (or what is it?) ?

I have already asked about this issue on that forum website. Based on that I guess my USB modem setup (without router providing static IP) is not supported in Openhab. As possible solution I am buying router for SIM cards and will try connect my Raspberry to that router with IP address set to be always same. Will see if it helps.
