Hi Taymour,

If I decrypted ;) right the trace you have a configuration with two 
OpenSER servers:

             SIP                     FIFO
OpenSER1 <==========> OpenSER2 <------------>  SEMS

Is this correct?

If so, be sure that the two OpenSERs have different fifo files 
configured (to avoid overlapping) and also check that SEMS writes back 
to fifo belonging to OpenSER2 and not to the one of OpenSER1 !!

regards,
bogdan
