FXT003 running 7.45 firmware
We have a problem in the fields where unit would suddenly loose communication over GPRS/3G and Ethernet at same time. Ethernet link light on IESM card goes off. Modem is still operational (we can contact it using data over voice channel).
It seems that WIP dies for some reason. Rebooting the modem always brings it back to life.
We do have number of safeguards around failed GPRS/3G connection and closed sockets that would eventually reset the modem if a problem can not be rectified in timely manner, but none of those safeguard trips, making me think it is something internal to OpenAT that causes the issue.
It is unfortunate that this problem is intermittent and we can not reproduce it in the lab, but we have number of those failures on different modems in the field.
Did anyone saw such a behaviour before?
