command wants to run 60000 calls, but only run 1700 then stopped

[bayroncalderon]

Looks like this would be the fix #635

[lemenkov]

Please check the latest master branch and report if PR #635 indeed fixed this issue

I got the same issue on macos Sonoma 14.1.
It seems that when you use IP4, there is an issue in the bind command because it uses the size of socket_storage by default (which seems to be too large for IP4).

bind(rtpsocket, (sockaddr)&address, sizeof(address)) ` gives "Invalid argument" when using IP4 address

bind(rtpsocket, (sockaddr)&address, sizeof(struct sockaddr_in)) works with IP4.

I guess a test should be added to adapt size argument before the binding call.
