FMM920 fw04.00.00r13 random reboots

Hello everyone,

I recently got my first tracker (intending to roll-out in entire fleet) and in first few days I already got some strange issues. Most of the time the tracker logs and submits data to server as expected. However, at random intervals (e.g. yesterday not even once, today twice at 11:00 and 11:42) tracking stops for short while and later it continues. I originally thought it is an issue on my network, but it turns out the “Last start time” in the Configurator corresponds exactly with the time when my server starts receiving data again after the outage. AFAIK “last start time” is similar to boot time on computers.

Out of curiosity, I downloaded the Dump and it contains folder “2_fail” with two files: “crash.dmp” and “MemoryDump.bin”. This IMHO suggests that it is really crashing/rebooting. Is there any known fix or troubleshooting guide please? Happy to submit any details to engineers for debugging, but I guess this forum isn’t ideal for sending sensitive details.

ps: I am new to this system and I apologize in advance if this is something simple and obvious.
