Plex on Synology DS918+ crashing

my plex has been crashing lately tried installing all types of servers going through some trouble shooting threads posted here unfortunately cant figure out why it still crashes . last crash 17:50 if anyone can help and see whats the issue

same thing . cpu goes to around 98 % when playing any type of movie runs for abit and then gives me ( couldn’t create playback session for this item ) on atv . Tries on my Samsung tv as well same issue gets disconnected .

Nas has a static ip

ATV has a static ip

did what you told me on the router to reserve the mac address as well same issue . This issue has never happened till after I installed the 6.2 and more upgrades on plex media server in the past month not sure if it has anything to do with that but previous to that I would have 3 people remote and on local network watch movies with no cpu fire up or crash or disconnection .

FYI, DSM 6.2 is released.

Synology® Announces Official Release of DiskStation Manager 6.2
Bellevue, Wash. —May 23, 2018—Synology® Inc. today announced the official release of DiskStation Manager (DSM) 6.2,…

PMS 1.13.2 running fine on my DS918+ / DSM 6.2-23739. I always stop/uninstall old/install new when updating to a new PMS release. Plex client v7.0.3 on Nvidia Shield working fine. No problems.

Ok tgis is what i did last night and seems to be working for the momment on atv . I went to the router and reserved the ip for the nas and set ip on atv as automatic and it went stable again . Watched a whole movie with no drop down .

So it seems that the network is what is causing the issue for now . ( Thanx trumpy )

I will leave this here and if i find anything else will update the issue .

Yes rebooted all devices after the setup you told me about to do in the network . Till now its running smooth . Thanx again will be testing more for next couple of days if anything new occurs ill post log so you can see .
