On Synology, this isn’t how we increase the number of directories PMS can monitor. We used to do that but Synology didn’t like us changing it so they obfuscated it.
HOWEVER
It’s best to verify we need to increase the table prior to just asserting a new size.
Are there “No space left on device” errors while Notify is initializing ?
If we do need increase, we need to do it this way
Then restart DSM.
Per the CPU stuck, I’d like to see some logs please; DEBUG logs ZIP; gathered about 2 minutes after PMS starts and having sat as idle as possible during that time.
