Convert caused multiple force reboots...

Ok, first off, I realize this is likely something up with my system more than it is something with Emby. But I wanted to post about it just in case anyone else sees the issues so maybe we can narrow down where issues might be coming from.

 

Unfortunately, I no longer have the offending media file as it was replaced in the end. But here's my scenario.  

 

I was playing around with Convert. I decided to try it out by converting some of my insanely high bitrate files into smaller lower bitrate files. I chose my largest movie file and started a convert. I had used the replace function. It got to about 79% and it occured to me I shouldn't replace it till after I had been able to verify exactly how convert behaved, so I canceled it. I restarted it with the option to place it beside the original so I could compare. This started a series (of about 10) force reboots. But only after I restarted the convert. It would do it 5-10 mins after restarting the process. Sometimes 30.

 

And I mean FORCE reboots, nothing in any logs. It would just be humming along and the server would restart. No errors, the logs in fact would be cut off sometimes mid line. It was an instant reboot issue. I had recently had a power supply fail, and I figured it was my box. That the power supply had damaged something. Or that it was overheating. So after the first couple of reboots I ran stress and watched my temps. 

 

Stress ran fine for a very long time. No reboot. Temps stayed good. Retried convert. Got reboots again. Keep in mind my server has NEVER done this before. And it transcodes often as I have a number of users. I ended up converting some other content. No reboots. I've since done some other movies, no reboots. Just that ONE file....

 

After the last reboot I didn't restart a convert, but at some point it restarted itself, I'm guessing the sync task ran and restart it. When I woke up the next day I discovered at some point it had been able to finish the convert and I had a new file beside my existing one. But I did see evidence of a few more reboots during that time. Hasn't rebooted since even tho I've converted more large files.

 

However, at the time I was still thinking something was up with my system, so I deleted the file in favor of the new smaller one. But since it has not happened since with other large files I'm now thinking it was something up with THAT file. Or something to do with the fact I canceled it then tried restarting it. 

 

I throw this out there just in case anyone else has seen or sees issues. Extensive testing points to it being something with that file and not a system problem, just took a few days of testing to figure it out. Wish I still had the original, but  it is what it is.

Hi, yes if the entire machine is restarting then it sounds like a possible hardware problem to me.

I agree Luke, and I wasn't going to even mention it due to the fact I really thought my box had issues. However upon stress testing and being able to convert multiple other files without issue since, I just wanted to throw it out there in case anyone else is seeing something like this, and isn't mentioning it for the same reasons. 

 

Either way, it wouldn't be Emby a fault, but ffmpeg. Just fishing to make sure it's not something possibly bigger.
