BG2 with pppd hang-ups | Thales IoT Developer Community

i was observing a strange effect. We have about 25 BG2 modems in field. The host is a linux system running pppd (version 2.4.5). The modem should be always connected; the pppd is configured with persistent (see below my configurations).
We have got recently some complains from the field, that the communication stops working and only disconnecting the modem from the power supply and connecting it back readable the communication. This happens sometime once a month, sometime 2-4 ***** a week.
I have analyzed the pppd log and found out that the modem dose not answer at a certain point in time:
- The LCP Echo Req is not answered anymore
- pppd try to redial, but the modem dose not answer the AT commands any more
Did anybody face a similar problem?
My pppd options:
connect "/usr/sbin/chat -vf /etc/chatscripts/icb"
The chatscript :
ABORT 'NO CARRIER'
Thanks for you help,
