Error: ENFILE: file table overflow

[0x5e]

The bug

I'm running immich server on macOS, and store photos on the external drive with exfat format. Mobile app stucked when backup photos, and I see the error logs from server side. Sounds like the file numbers are too much and I delete many of thems, but after a while problem occurs again.
I guess the root cause is from the drive format, but anything we can do to optimize it?

1. the mobile app didn't get any errors, users didn't know the reason and just waitting.
2. soooooooo many folders on upload/*/ with no files, can it be create only when it's needed?

Thanks for the developer team, this project is great :)

This is definitely due to the exfat filesystem, and there are also many other good reasons to not use that for your important files ;) So I would recommend switching to something else.

This is a macOS vs exFAT problem, not a bug in Immich. You can look into how to increase the number of file handles on macOS.

Not only an exFAT issue. I'm having the same problem on macOS with a Btrfs volume mounted over NFS.

[mmomjian]

Seems like a Mac issue, this was the first hit I found: https://stackoverflow.com/questions/45004352/error-enfile-file-table-overflow-scandir-while-run-reaction-on-mac

[pyro2927]

For anyone coming here in the future, setting resize=65536,wsize=65536 in my NFS connection string seems to have resolved the issue.
