AFAIK, you should get two process for each class you define in
musiconhold.conf, they will only consume CPU while there is one or more
people in that MoH class, but the process won't exit until asterisk
does. Frequently, if asterisk crashes, it won't get a chance to kill the
mpg123 processes, and hence you will end up with a lot of extraneous
processes. The best fix is to work out why asterisk is crashing, and fix
it.
