Since moving to linux, I regularly am getting multiple instances of M running, not sure what is causing it, but usually when it happens it takes all of mystic down.
Rolling back to mystic A33/Linux 64 seems to have resolved this problem for now.
Odd that it made a difference for you, I run it without problems but only on point systems - one of which gets no traffic and the other (this one) little traffic. It's my main system that I do most things with, but I haven't seen a problem with mis running multiple times. Still I do reboot at least one a
week to update the Win10 side of this dual boot setup (otherwise the updates take forever when I try to boot Win10). A33 seems to be the best on the Pi,
A34 seems OK under Ubuntu 14.04 or 16.04 32 or 64 bit, all seem fine here.
Good that A33 runs OK as that's the first one to offer correct MSGID handling.
