Bug#638748: timidity sometimes sits on CPU

["Mark T.B. Carroll" <mark@ixod.org>]

Package: timidity
Version: 2.13.2-39+b1
Severity: normal

I leave timidity running (from the init.d script) and use ALSA's aconnect to have it listen to my USB MIDI keyboard so it can generate sounds for it.

Sometimes the timidity process gets into a state where it sits on the CPU and isn't making sound from my keyboard any more. I don't see anything illuminating in /var/log/. If I kill and restart timidity then it is okay again.
