When experiencing connection lockups and ultimately the Flint2 becoming completely unresponsive, it looked like zombie processes left over from crontab entries might have been the cause:
modem_sim_status_check.sh was scheduled to run every 10 seconds!
Removed the crontab source files and disabled the sms_manager service and removed the entries from the crontab and so far no lockup has occurred.
Is this a known issue or has anyone else seen something like this?
Could you please provide the following details so we can investigate the issue further:
What is the firmware version of the Flint 2?
When the Flint 2 becomes unresponsive, does it recover on its own, or does it require a reboot to restore functionality?
Please SSH into the router and run the following command to save the system logs to flash so that relevant information is not lost after a reboot. If the issue occurs again, export the logs and send them to us via private message for analysis:
uci set system.@system[0].log_size='512'
uci set system.@system[0].log_file='/root/system.log'
uci commit system
/etc/init.d/log restart
