Just for an answer.
This is an issue with file descriptors limit of your OS. ejabberd opens new port for each new connection and this new port happens to use file descriptors. By default file descriptor limit is 1024 (Check with ulimit -n). Increase this limit to 30000 (with ulimit -n 30000)

So it seems that your stress load is too high, reduce the number of users or deploy more than one ejebberd. You could give us more information on your test too to help us helping you.
