So the nameserver\nshould advertise the removal of the node to all remote and local observers\nand free the node finally. But currently, the nameserver doesn't free the\nnode memory even after processing the BYE packet. This causes the node\nmemory to leak.\n\nHence, remove the node from Xarray list and free the node memory during\nboth success and failure case of ctrl_cmd_bye()."
