I’ve been trying but have not been able to get the system to fail as you describe.
On thing that is interesting is the fact that the log entries are stopping and not showing all data. SD cards have a limited number of write cycles. The recommendation is to use something else like a flash drive to store log data.
How long have you been using the SD card in your system?
I use a SanDisk Cruzer Fit 8GB USB Flash Drive in My system. it is small enough to fit inside the OSPi case. Instructions for the setup are on the wiki:
I don’t know if it is a problem with your SC card but that is one possibility. I will keep testing but so far I can’t find the problem.
