Could be fragmentation, but that has to happen due to operations in that 
process. What is done via fifo affects only the memory of fifo listener 
process. In SIP workers process can be due to lot of SIP messages 
processing -- parsing, script variables, db operations,...

Compile with memory debug and see the log dump, that will give more hints:
