Occasional CPU overload, usually when closing player
jwflory opened this issue · 10 comments
I've noticed lately that the mpris-scrobbler process on my system will max out the CPU utilization on my system. My laptop fan or desktop fans will begin spinning up, and looking at htop shows the mpris-scrobbler process as using 100% of my CPU. Restarting the systemd service is a quick fix and CPU usage goes back to normal, but it still happens about two to three times a day.
I haven't been able to trace the issue down, but I think it usually has to do with closing a music player. The only music players I use are the Spotify desktop client and occasionally Lollypop.
Any ideas on how to capture more useful debug info? I'm not an expert on C but happy to do anything I can to debug. I really appreciate this little app, thanks for working on it!
Hi, yes I know of this problem and I get it also when using Spotify as a player.
I wasn't able to solve the issue so far, but I didn't spend that much time looking into it either. I just restart the scrobbler. :(
I think I have the problem isolated in the loop that reads from dbus the mpris properties and metadata for the current track.
Unfortunatelly my main focus is somewhere else, and I'm not sure when I'll be able to look more into it.
Bummer. Okay, thanks for the update. If you do get time to look into it, I am happy to help test and troubleshoot any way I can. Thanks for your time making this super useful tool.
@jwflory just to keep you updated, I've taken a break from my other projects and started working on mpris-scrobbler. There's a chance this would be fixed in the near future. :)
@mariusor Woohoo awesome! I'll be sure to get any new releases packaged up for Fedora/CentOS/RHEL. :)
@mariusor I will work on giving it a go and creating a pre-release / beta package in my COPR. Because of nuances in the Fedora package build system, it will make my work easier if you can cut a new git tag first. I can wait to publish in official Fedora repositories until some issues are confirmed and/or closed first.
Hey, in the meantime I had some crashes on my machine, so I'm not fully ready to do a pre-release tag. I'll give it a couple of days for testing on my side and then I'll let you know. Thanx.
@mariusor Thanks. Because of silly constraints in the Fedora build system, and that I am still a RPM scripting novice, make it hard for me to build from untagged commits. A tag (even if just a tag named by the date and not a new version) simplifies my workflow greatly for downstream packaging.
Hi, just confirming I upgraded to v0.3.91 today. Will monitor CPU usage and scrobble reliability more closely for the next few days.
