Subject says it all
MD crashes (and I get the OS crash dialog). MD goes away and can be restarted.
Mono sticks around, and has to be hard killed (kill -9 or using Activity Monitor)
Happy to run something to interrogate it, but dont know what. It happens most times that MD crashes (which is 2-3x a day, tho I never lose data, which is good)
What vesion of Mono do you have on your system?
When this happens, can you go into a console, and type this:
(gdb) attach PID
(gdb) t a a bt
Where PID is the process ID for the runaway Mono process
Absolutely, will do.
I have whatever the latest is on the beta channel for MD. I installed an Mono update a couple of days ago (maybe late last week?) when I moved from the stable to beta channel.
HOWEVER I think this was happening before that, but I could have been on a mono beta then too (I switch back and forwards a bit)
Can you please double-check the Mono version in the About dialog? There was a known issue with 2.10.7 to which this sounds very similar.
Touch wood (WTF?) it hasn't happened today. But I have:

Pleased to report that with the above config, I've had NO crashes ALL weekend. LOVELY. (close the case, IMO)
That said, I did just quit out and hat mtouch hang at 99% CPU used. I tried the gdb attach, but it seg faulted on me. I had to kill -9 it.
Marking this bug closed since it was fixed - if you have the problem with mtouch again and have a trace, please open a new bug against mtouch.
