How many copies of the mupdate master should run?

Probably related to the preforking mechanism.  One can
reproduce the behaviour with the pop3 and imap service 
daemons.  Ours is Cyrus 2.2.13 on Solaris 9.

  prefork=2 causes 4 instances to be started,
  prefork=5 produces 10 instances of a service daemon
