Gemalto/Cinterion EHS6T USB modem hw watchdog problem | Thales IoT Developer Community

I have a EHS6T USB modem with firmware version (ATI1 command):
I have configured hardware watchdog with parameters:
I have a serial RS232 connection between modem and linux embedded system; linux initialize the the modem and initiate a data connection (internet connection) thru pppd; all works good and system ping 126.96.36.199.
The modem is also connected thru USB and a simple program send command via ttyACM0 (1st pseudo serial port) to the modem with command
after this command, every 30 seconds the system send two AT command
All works fine with older firmware version, but now the Gemalto EHS6T reboot after random time from few minutes to 2 hours. If i disable the watchdog the system does not randomly reboot.
I have tested with default value for "Serial/Interface/Allocation" ("0") and with value "1", no difference, the modem does random reboot.
How can I resolve this issue?
