iSH crashes persistently on my device [testflight dump]

[xloem]

I’ve never gotten iSH to run reliably, even when not allocating ram. It usually runs for a bit, and then starts crashing repeatedly and relatively quickly when relaunched, often associated right now with launching vim or saving a file from vim. Often if I wait a while, I can then run iSH for a bit again.

I’ve found I can deter this crash if I frequently interrupt applications with ^Z and then type ‘sync’ to flush the filesystem and then resume them with ‘fg’.

On resume they run much faster briefly, and then I often need to do it again to deter a crash.

Sometimes it crashes on the ‘sync’ and then I do ‘sleep 5; sync’ to make it work.

Per comment on Discord, here's a dump from the main process. This happened when I ran pip. Yesterday, I ran pip successfully using the workaround above. iSH-2023-12-28-070109.ips.txt

Per request on Discord, here are dumps from a crash when attempting to run the new system package upgrade, which doesn’t provide for my ^Z workaround. iSH-2024-01-27-090818.ips.txt iSHFileProvider-2024-01-27-091102.ips.txt

I’ve found I can pursue completing an upgrade by separating packages out with a command like apk upgrade --simulate | grep 'Upgrading' | cut -f 3 -d ' ' and addressing them individually. It works fine in a for loop brute-forcing through the crashing because it will resume where it left off,

Engaging suggestion on Discord, I am no longer seeing this specific crash after removing iSh from my Files sidebar 🎉. I suspect the crashes started after I began downloading files directly to /tmp from Safari.
