When using DSR , interface queue type is Queue/DropTail/PriQueue, no. of node 50; the Segmentation Core dumped occured. But when using DSR, interface queue type is CMUPriQueue, no.of node 50, then it simulates sucessfully. When using AODV , interface queue type is CMUPriQueue , no. of node 50; the Segmentation Core dumped occured. But when using AODV, interface queue type is Queue/DropTail/PriQueue, no.of node 50, then it simulates sucessfully.

Therefore I have code my tcl script to use different interface queque: AODV using Queue/DropTail/PriQueue DSR using CMUPriQueue

Questions: Does any body know what is the reason for this? What is the difference between these two queues?

I apreciate any help in advance.
