Well, this a something that has periodically shown up for people,
and the reason it happens is really something we'd like to find.
Presumably, you aren't even using midi with ardour at all, right?
Before you resize the midi pool, could you enable midi tracing
in the Options Window (midi tab), and watch the console output
for anything the next time this error is triggered?
To increase your midi pool: edit the file libs/ardour/session_midi.cc
and look for the line near the beginning:
MultiAllocSingleReleasePool Session::MIDIRequest::pool ("midi", sizeof (Session::MIDIRequest), 128);
Change that '128' to something bigger.
