Please turn off verbose logging. Debug is sufficient. Verbose adds a lot of additional, usually unnecessary, info to the log files. As a result, they wrap too fast and the desirable information can be lost.
From Plex Media Server.log (2023-04-24):
Apr 24, 2023 16:12:49.239 [0x7f039b3ffb38] ERROR - [Notify] Failed to add watch for "/volume1/Multimedia/Movies/English/2D/C/Crucible Of The Vampire (2019) [BluRay] [1080p] [YTS.AM]" (28: No space left on device)
You’ve exceeded the Linux inotify limit. This is common and easily rectified. Remember to reboot the NAS, not just restart PMS, after increasing the limit. It is a Linux, not Plex, limit, so the NAS must be rebooted.
See FAQ 16: Increase the number of folders Plex can monitor.
Adjust the limit and see how Plex responds. If it does not correct the situation, upload another set of log files.
FYI, if you want to see PMS hit the notify limit, look in the same file and count the DEBUG - [Notify] Now watching entries. There are 8192, the default limit for Synology NAS.
The last entry is Apr 24, 2023 16:12:49.239 [0x7f039b3ffb38] DEBUG - [Notify] Now watching "/volume1/Multimedia/Movies/English/2D/C/Crows Explode (2014) [1080p] [BluRay] [5.1] [YTS.MX]".
The next line in the log file is the ERROR entry listed above.
