Description of the bug

with the latest jellyfin updates, the server creates millions of temporary .jpg files by filling the ext4 inode
when I reboot the system it takes hours to delete all the temporary files, and I have to delete them before the reboot otherwise the server stays booting for hours.
my next test is to put a memory disk in fstab for the /tmp folder
the logs show no errors on these files

Reproduction steps

open folder /tmp/jellyfin/nnnnnnnnnn/*

I was able to reproduce. Just doing a library scan places jpg files in /tmp/jellyfin. After the scan finished the files were not cleaned up.

The QNAP system frequently experiences RAMDisk / or /tmp capacity shortage errors. Because the/tmp capacity of my qnap (464c2) is only 64M.

We recommend you set the TMPDIR env var to point to an ssd to not use the system temp if it is that limited. 64MB could be too small for trickplay temp in some cases.
