You're right, I didn't mention system info. I have version 0.60.7
running on Archlinux, standard kernel. Jack is running on laptop
built-in audio card with:
/usr/bin/jackd -r -t2000 -dalsa -dhw:0 -r44100 -p2048 -n2 -Xseq

I found the hanged note stops if I change the midi channel in bristol.
Not sure if the note is still there playing when I change back to the
original channel, I'll try it next time it hangs.

regards,
renato
