Legato R12 shutdown when mobile data connection drops

[annaertd]

Hi,
the issue is still there, and I’m convinced that there could be a link with my other crash issue:

modemDaemon crashes due to 'cm radio off' command

Hi, I use WP7607 with R12 (Legato 18.10.3) with a mobile data connection (rmnet_data0 interface). As a test, I switch of the radio via the command line of the target: cm radio off Immediately, I get a system crash referring to modemDaemon ILLEGAL ADDRESS 0x40. See log in attachment. What could be the root cause? greetings, annaertd cm radio off makes modemDaemon crash (32.5 KB)

The only useful stuff I can find in my logs, is modemDaemon service-calls just before the reboot.
Unfortunately it doesn’t contain enough info for me to understand what’s going wrong.
