Hi Guys,
Been searching through the forums here and on Synologys site to try and get an answer to this, but I've not been able to solve it yet so thought I'd just ask you guys direct.
Been running Plex server on my mac for about 6 months with no issue and finally wanted to get a dedicated box that did a few things and didn't require me to have the Mac running 24/7 to be able to access Plex, so started researching Plex compatible NAS's. Picked up a DS216j as it seemed to tick all the boxes and have been setting it up over the last few weeks.
My setup when I had the Plex server running on my Mac was to have Plex look at my iTunes TV Shows and movie folders. I'm an apple guy and want to keep using iTunes to manage the films and it worked perfectly. Add a film to iTunes, Plex picks it up, shows up on everything else - Xbox, iOS apps etc. Perfect.
When I was setting up the NAS I copied my iTunes folder structure from and library over to the NAS and then pointed iTunes on the mac at the network drive that was storing it. Essentially using iTunes on the mac as a front end for the library on the NAS. Not a supported use case for iTunes but as long as the mac and NAS are talking to each other it hasn't been an issue.
On the NAS I installed the latest version of PMS from the Plex site and set all my libraries up, pointing at the same folders on the NAS as they had been set up on my mac.
All has been working flawlessly EXCEPT for one thing. After a few hours/days of Plex happily running on the NAS it will start to have a runaway Plex Media Scan process on the NAS that uses 30-50% of the CPU.
I've told Plex not to generate thumbnails in the Library settings and have also told it to not scan folders for incremental changes in case that was causing the issue but I still can't seem to solve it. A restart of the NAS will see everything go back to normal and it will happily run without issue for some time before I notice that the process is stuck again. Manually asking Plex to do a library update won't cause the process to spike the CPU either.
Reading the forums here made me think that the scanner was getting stuck on a particular file but I've been through the logs and can't spot anything. I've uploaded the logs to here: https://dl.dropboxusercontent.com/u/4877406/Scan Logs.zip in case anyway wants to have a look and try and spot something that I've missed.
I'm so close to having the perfect setup with this NAS so any help anyone can give is much appreciated!
