Plex causing computer to Reset... sort of

So here’s the strange thing that’s happening for me: When I stream to my roku 3 in the plex app, it causes my computer to restart… usually within 10 minutes. it crashes at other times too, but I’m not sure if it’s just PMS running in the background or what - but Plex is guaranteed to cause it.

Is this a known issue of some kind? I’ve replaced + upgraded my wireless adapter, and most of my software logging has shown everything to be normal + working fine… no overheating issues or anything like that. Given that it’s guaranteed to happen when I’m streaming something with plex, I’m hoping I might get some insight here!

If PMS is transcoding, it will put a load on your computer’s CPU.

The hardware is self protecting and will, if necessary, hard reset and/or power off (depending on OS and overheat abatement strategy).

It would help if we knew more of the particulars. Computer? OS? Transcoding active when the reset occurs?

Log files help more… and if Linux, system log files. (journaltl -xe | grep -i plex output)

I’ve done a lot more troubleshooting and it appears Plex is only sort of to blame.

I’ve run much more intense stress tests than Plex transcoding, and no crash. I’ve run the same files from my Mac and roku ultra, and no crash. The issue appears to be localized in two ways: having a tonne of tabs open in chrome, and streaming from my roku 3. If I stream from my roku 3, my computer barely last 5-10 minutes. Any other machines and the sky’s the limit.

I’m reading that there are a lot of plex/roku 3 issues with the latest firmware, so I feel like that’s at least partially to blame. I’ll followup to this post with a log when I have a moment to set it up

Check your Roku firmware. You’ll probably find it’s version 7.7 firmware which is, unfortunately, known for having all kinds of streaming issues not only with Plex.

You can write to roku, tell them you want the 7.6 downgrade until they fix it . Yes they will argue with you but you will get it (ssmith@roku.com is having trouble keeping up with demand).
