  Hmm... see doc/bugs for some more information.  Getting full back traces is helpful.

Of course you have much stuff to do, you're responding *for free* and it's a bit hypocratic to say it needs some hours to write a reproducable explination of the bug (escpacially with the PROXY protocol forwarder etc.), but it's much faster. If it's better as github issue, i'm going to open one. 

  Sure, that's good.

  That looks like a busy loop, which is not good either.

  I've done some preliminary tests with haproxy, and it seems to work.  So I'm not sure what else is going on here.
