Hi! I've been running the same image transformation program for a while, but for some reason it keeps crashing today. There's no error message; my code runs for like 5 minutes and then before completion, the Matlab program quits.

I'm running Matlab_R2022a on macOS Monterey 12.3.1. Any advice would be appreciated.

did you check if there are any "exit" or "quit" commands in your program ?

Yup. There are no exit or quit commands.

One thing I would check is for overheating https://www.bestmaccleaner.com/mac-temperature-monitor/

I also suggest testing RAM https://support.apple.com/en-us/HT202731

I also checked temperature and RAM.

I ran the diagnostics and it says there were no issues found. I checked the temperature and it is hotter (usually its 77 degrees F but it gets to 87 with Matlab open), so I don't know if that's an issue.

I checked Memory Used/Allocated through Activity Monitor and it seems like a very big chunk of memory (26 GB) is being used/allocated for the Matlab process so I don't know if that's where the issue is. Let me know if you have any suggestions.

I think it might be theoretically possible for MATLAB itself to crash from running out of memory. Normally running out of memory would be noticed at the computation level, and would result in an uncatchable exception . However, in principle the amount of memory in use could be almost at the limit, and then when MATLAB itself needed memory (such as to open a variable in the variable browser) then potentially MATLAB itself could crash, I suspect.

But that does not sound like what is happening to you.
