Packet Trace Error while Sending the Packet

[Hassam Mughal]

Greetings everyone!

I am trying to run the on off application on custom time in simulation. The packets to be sent have packet size = 1024. However, the packets are not being sent and I am getting SIGSEGV, segmentation fault error. Following are the code snippets and log and debug pics;

In my case, I am trying to count the sequence number of each packet at each node, therefore I have converted m_seq to int array and passing the node id to it.

Any help or guidance in this regard is highly appreciated.

Thanks

Best Regards,

Hassam

There is a segfault. The memory location you are trying to access is probably busy or not assigned. You will have to check that.

Thanks for your response. Is it because I am using the array? Is there any other way to keep track of packets of each node? As I need to calculate throughput at each node, also calculate the data transfer between nodes. So need to have the exact values of packets being sent and received at each node.
