If you use cyrus 2.2, mupdate should restart automatically almost
immediately.

Otherwise, I'll need to see a core dump backtrace (and since it is a
threaded process, it is likely that getting a useful one will be hard).

I think the only times I ever saw our 2.1 mupdate master crash is when it
ran out of file descriptors...  (This is also fixed with some configurable
limits in 2.2)
