Yes this is exactly what is expected.  SipTransaction objects in the
code have a many-to-one relationship with an actual sip call.  Such
objects are used to hold dns lookup info, forking path info and other
internal information.  They are removed from the SipTransactionList
after a timer fires.  You should see the remaining 476 objects deleted
at later times in the log (possibly all at once, possibly in groups.)
