Serviio

Found with a previous update the service would end up consuming a large - 80%plus - amount of CPU resources.
I've removed the entire media library config so no files are present, I've uninstalled, rebooted, reinstalled and still the CPU usage goes sky high.
Log file seems to indicate it's looking for playlist changes?

Any pointers where to start?

Thanks in advance

I've set debug mode and will post log file once the services runs away with it self again..

Took 4 hours to run away but the serviio service hit 96% cpu usage.

Hmm, nothing suspicious in the log.

Do you see the same when you run via bin/serviio.bat rather than the Windows service? (you'll have to stop the service first)

Having not seen it over the last couple of days having launched Serviio via the batch file rather than the service, the Java process has run away with itself and is averaging 90% cpu.

Had the same CPU usage problem on installing version 1.7 as CPU and disk usage was at maximum. Also had exactly the same problem when installing a previous update release.

It runs on my PC (with slow processor and small memory) for around a day or so before it sorts itself out. My server is on 24/7 anyway.
Seems like it is reindexing the library but a very long time even for that.
I have 8500 audio, 6000 images and 100 video files in my media library for size comparison. I use the Serviio service as I find it works well.
After long patience the high usage sorts itself out and is now working perfectly again with normal CPU usage without further intervention or action.

Just for comparison my PC is running a 6th gen i5 6600K with 16GB RAM

Barely 2 minutes into boot and it's 90+% leaving the entire system unresponsive...

there are some problems with acquiring the IP address to use, check the log file. Did you select a bound IP address in the console? Is that still valid?

I had noticed that in the logs, it was originally trying to bind to a device that's no longer connected, bind settings are currently set to automatically detect, but still get the lockups.

I've just now set an IP reservation to a different address, will see if that makes a difference

Well, the initial attempt at a different IP via dhcp reservation failed, set a static IP at 20:11 and approx 4 hours later the service ran away at 90% + cpu again..

A couple of posts to follow with debug logs timed from 8:40 this morning till 7:20ish this evening.

At some point during this time something happened again to cause the serviio service to consume 96% cpu, it also started this last night and I left it running overnight to see if it would clear but still 90+% at 7.40am

2nd post with first 3 logs (in time order)

Note, had to edit these ones removing the date to reduce the file size enough.

3rd post with the last of the logs - in time order
again had to edit 2 of these to get the file size down, simply removed todays date

Thanks, there is nothing in the logs that looks out of order. That makes me think it's something to do with your system, or in particular how Java / system libraries talk to each other.

If you want to try digging, download VisualVM https://visualvm.github.io/

You will be able to attach to the Serviio process and see used memory, CPU etc. Ypu might be able to figure out which thread is taking all the CPU. You can also take a snapshot (when it's running high) and send that to me to have a look myself.

Hi, thanks for the link, is running, but how do I attach the Serviio process?

If you're running Serviio on the same PC it should be under Local folder on the left.

Have twigged that VisualVM won't pick it up if it's running as a service so have launched via the batch file as mentioned previously in the thread..

Will report back with results.

Hi Petr

Application snapshot attached, compressed as .apps extension wasn't allowed..

and again overnight, included threaddump this time, heap dump is huge..
