My first guess is that you are running out of file descriptors.  It
looks like each thread creates a new socket, calls send, then calls
recvfrom repeatedly, never closing the socket and freeing the file
descriptor.

You should close the socket after receiving a response.  Alternatively
you could see how to raise the per/process file descriptor limit for
your system (for bash, try looking at the ulimit command--the exact
command and syntax depends on the shell you are using).
