Plex causing my Synology NAS to hang

Hi All,
I’m having an issue on my Synology box where it’ll hang randomly. I’ll be able to PING the Server, but I wont be able to access it via web browser, through the DS Apps, Telnet, SSH nor will i be able to use Plex.
I have logged a call with Synology who have investigated the issue following log files i’ve sent them and they’re pinpointing the issue to be related to Plex. I asked them to narrow down what Plex might be doing at the time, but they didn’t answer me. The odd thing is even if i’m not using Plex, the issue still occurs.
I have attached the log files from my Synology box and also the Plex log files. The last time the Server hung was on 17th November 2020 at around 13:15.
Would anyone be able to dig through both sets of log files and see if they can find out the cause.

Many thanks in advance!

NAS Model: DS420J
DSM Version installed: 6.2.3-25426 Update 2
PMS version: 1.20.5.3600-47c0d9038

Hi @trumpy81,

Many thanks for the time you have taken to look into this. Also apologies for missing certain details off which will hopefully be clarified below.

I was certainly unaware of known memory leaks with DLNA. When I run Plex on my Xbox One, it runs fine. You are correct with regards to the LG TV. I do have one of these and on the TV is where I get the intermittent issues. One day i’ll be able to run Movies and TV Shows fine, the next it’ll struggle and hang. As you also correctly said, the Server does go “offline” but does also sort itself out and come back online on its own after about 15-20mins…
Its something I should have done ages ago, but i’ve since enabled the Resource Monitor widget on my Synology box. I’ll keep an eye on this especially when I run Plex on my LG TV.
Would rebooting the Server every other day do more harm than good? I guess a question to ask the Synology guys (unless you are able to answer it) is is it possible to restart the DSM rather than restart the whole Server?

Again, many thanks for your time to look into this for me. You’ve been very helpful. Kudos to you.
