99% CPU and errors in log

[oldschool 14]

Just recently MB3 has had almost 99% CPU utilization. I have to end the process and restart the server. This has been going on for the last week or so. I'm not sure if it has to do with MB+ that I recently installed, but I uninstalled it and I'm still having the issues. I have a large media library, so I'm not sure if that is causing the problem or not as well.

 

I'm on 3.0.54.82.1. I was getting DLNA errors and subtitle download errors, so I turned off both of those features as well, but I'm still having problems with the server being unresponsive because it is processing something in the background.

 

A reboot solves the problem, but not for very long. This last one it was only about 3 hours before the CPU utilization crept back to 99%.

If you look in task manager, what process is actually eating up the CPU cycles?

[oldschool 14]

MediaBrowser.ServerApplication.exe*32

 

Also, kind of weird and maybe related, my ServerWMC on a different PC keeps crashing, and so when I start MB3, it has recently reported that it can't refresh the guide. I start the service again on the other PC (and I've rebooted it numerous times as well), but ServerWMC has been unstable lately.

Here's the last error in ServerWMC:

Does it happen if you remove the ServerWMC plug-in?

[jds828 24]

I had ffmpeg.exe eating up nearly 70% on an i7 3770k.

 

I can't think of anything I altered but it's now dropped to between 10 and 20%. Still a tad high but much better than before. It was doing in on both remote and local so not sure.

[oldschool 14]

I haven't tried. I could try it now and wait and see if the problem returns.

[oldschool 14]

I don't see a place where I could remove the setting on the LiveTV tab.

[oldschool 14]

OK - I uninstalled the plugin. Sorry - I was looking at the configuration page.

[oldschool 14]

So, it's only been 1 1/2 hours and I'm back to 99%. I removed the ServerWMC plugin and I'm still having the same issue.

well same questions apply as before, what processes?

[oldschool 14]

Same one - MediaBrowser.ServerApplication.exe*32 is the offender. In reality, everything else besides "System Idle Process" is around 2% or less.

 

That's the only one I have running for MB3 on this server. I've seen up to about 900,000K in memory utilized by MB3 as well when it gets to 99%.  It's been running for about 5 hours now, and even though MB3 hasn't been used very much during that time, it's hovering around 50% CPU.

[oldschool 14]

Another 99% utilization bout this morning.  Here's this morning's logfile.

Do any tasks show as running in the Scheduled Tasks panel when this happens?

[oldschool 14]

Hmmm, do you want me to provide a WIndows event log on this? Looking at the page for reporting errors, it describes how to view the Event Viewer > Applications and Services Logs > Media Browser, but I don't have that on this server (Server 2K8 R2), so I'm not sure if that's the logs you're asking for.

 

I haven't "caught" MB3 in the act of jetting to 99% so far, so I couldn't tell you whether one of them is running during the time. I can provide a list of the scheduled tasks on the system:

 

[ebr 15584]

No, scheduled tasks in the server...

[oldschool 14]

It doesn't look like I have any scheduled tasks - the box is empty when I look at the Task Status -> Last 7 days.

[ebr 15584]

I'm talking about here:

 

 

Are any of these running when your CPU is pegged?

[oldschool 14]

OK - let me try to catch it when it is pegged. The problem is that usually the interface times out when it is at 99%, so I can't even see the page. I don't think it is resulting from a library scan because the scan happens when I reboot and it completes successfully. I was hoping the log file would show what is running and causing the error.

[oldschool 14]

The browser doesn't connect. I've tried refreshing the browser numerous times using the browser on the server and MB3 doesn't respond, so I couldn't tell you what scheduled MB3 tasks were running to cause it.

 

It hit 99% tonight. Memory utilization was/is 64%, so it doesn't seem to be running out of system memory.

 

 

I've uploaded a new log file for the latest lock up.

Okay, then I would start by removing all plug-ins.  Then, if the problem doesn't occur, start adding them back in one by one until it does.

[oldschool 14]

It's kind of weird. I rebooted yesterday and MB3 looked like it wanted to behave. CPU usage was negligible - like 2% all day. It hasn't pegged today, but it hasn't been used as much today. Right now it's at 50%, MB3 is not serving anything or isn't being used right now, and MB3 is showing 50% CPU usage. None of the Scheduled Tasks are currently running and it's still taking up 50% CPU.

 

This seems to be how it has behaved recently, and sometime later today I expect it will end up being 99%.

 

I'll start to remove the plugins one by one and continue to troubleshoot.

[oldschool 14]

I removed the auto boxset plugin, so let's see how this plays out.

[oldschool 14]

MB3 seems to be very well behaved since yesterday and removing auto box sets. I'll add in some of the other plugins and see if the problem presents itself again.
