smmsp is the sendmail submission queue runner. It's a seperate sendmail process that runs /var/spool/clientmqueue, which I believe is where Sendmail drops outbound messages before delivery (for security through privelege seperation). You might have a bunch of messages in the queue that it's trying to process. If that queue is empty, use lsof or fstat to see what files the smmsp user has open when the problem starts.
