I am using Ubuntu 16.04 and listening to music using Banshee. At a certain point the graphics interface greys out and the application is unresponsive.
If I launch ps, the process list is monopolized by an application 'Main Thread' which is taking in excess of 100% of the CPU time and has been running for 20+ minutes as of now.
If I launch pstree the relevant excerpt is
|-lightdm-+-Xorg-+-{InputThread}
| | `-{disk_cache:0}
| |-lightdm-+-upstart-+-at-spi-bus-laun-+-dbus-daemon
| | | | |-{dconf worker}
| | | | |-{gdbus}
| | | | `-{gmain}
| | | |-at-spi2-registr-+-{gdbus}
| | | | `-{gmain}
| | | |-bamfdaemon-+-{dconf worker}
| | | | |-{gdbus}
| | | | `-{gmain}
| | | |-bash---Main Thread-+-{Finalizer}
| | | | |-7*[{Main Thread}]
| | | | |-{Timer-Scheduler}
| | | | |-{aqueue:src}
| | | | |-{audiosinkqueue:}
| | | | |-{dconf worker}
| | | | |-{flacparse8:sink}
| | | | |-{gdbus}
| | | | |-{gmain}
| | | | |-{mono}
| | | | |-{threaded-ml}
| | | | |-{typefind:sink}
| | | | `-{vis-queue:src}
Waht does this application 'Main Thread' do? And is there a way to avoid pre-emptively this way of things going stuck?
