Is the TCP connection has been established, then there's no problem.
Thanks for confirming this. I talked with one of our people about this
and he said the problem could not be reproduced. What he used was not a
Debian 8. Also, web search did not turn up similar problems, so this
looks like something that is not a universal problem.
In other words, no real update on this yet.
Easy way to reproduce the issue, is to drop mysql traffic with iptables.
Then drop the traffic with 'iptables -A INPUT -i lo -p tcp -m tcp
--dport 3306 -j DROP' and hit the instance with radpwtst every second.
If the debian systemd set the open file limit to 1024, then the instance
will collapse within 20 minutes.
Thanks for this additional information. I have made a note about this.
