Recently my X55 (1.2) has starting crashing/rebooting frequently, I only got it in May this year and hadn't noticed any problems previously. I have setup some basic monitoring yesterday and since then it has crashed/rebooted 4 times in less than 24 hours.

I have only one X55 and no satellites so the setup couldn't be simpler. The logs get cleared when the device reboots so I can't see what is happening to cause the reboot. I suspect this could be to do with being upgraded to a new firmware but I can't see anyway of telling when/if the firmware was updated (I have the device set to auto upgrade the firmware).

After doing some googling it looks like a lot a number of people are having stability issues with Build 20231229 Rel. 43148.

Is there a known issue? Is there anyway to capture the logs from before the reboot to work out what is wrong? What else can I try?
