Recurrent "failed to set dtr/rts" issue on EHS6T | Telit Cinterion IoT Developer Community

I have issues with EHS6T ****ms. I use them for USSD via AT Command from LAN only. They Works fine for 1 day and then an "failed to set dtr/rts" error occurred and I'm no more able to connect to ****m NOR run AT Commands until a hard reboot. OS reboot doesn't fix issue either. I disabled power saving **** and disable PPP service.
Attached is the system Log with full errors.
Please need a help to fix issue as I'm using them for Enterprise Service in production.
