Dear J S, To check memory leaks , you can go for valgrind tool. Check the link below.
http://valgrind.org/ Sometimes, out of of memory occurs if the trace file is large. In that case, just keep the traces that u need and turn off all other traces. For example, u may turn on AGT only and turn off MAC and RTR traces.

I want to trace the queue also the packet loss... but i got an error when i execute the tcl script.. Please anyone help me to execute the code.... set gh [open que.tr w] $ns trace-queue $n0 $m0 $gh wrong # args: should be "_o3 self class proc n1 n2 ?file?" ???

Now when I tried to run my simulation for longer time (24 hours), the process was killed and the kernel reported out of memory. The ns process could only last for 3 hours of simulation time. Does any one know how do I fix this problem? I reviewed the page http://isi.edu/nsnam/ns/ns-largesim.html It suggest that I should remove all packet headers and add specific headers, but since I have 3 different types of packets (ping-ICMP, packmime-tcp and pareto-UDP), how do I implement this? Is there any way I can check for memory leak? Thanks JS ------------------------------ _______________________________________________ Ns-users mailing list Ns-users@isi.edu http://mailman.isi.edu/mailman/listinfo/ns-users End of Ns-users Digest, Vol 63, Issue 4 ***************************************
