I’ve been trying but have not been able to get the system to fail as you describe.
I’ve tested a bit more, and it seems to only happen when Zone 0 has an empty name? At least that’s when it’s reproducible for me.

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.
Sorry, I meant that when the ospi daemon starts failing it also stops logging anything. The card is fine, and I have an 8GB High Performance (30MB/s) SanDisk card in there.

As you can see from the log, when I have a blank name for Zone 0, the log file always says , ,, and I think that’s key to the problem, and when you suddenly get Index Out of Range issues.
