Port on downstream server gets corrupted #6664
After a while - multiple days with heavy load - the port part of a random server as shown in showServers() changes to a random value. This is not just a cosmetic issue, we've verified that the port is actually tried.
Steps to reproduce
I'm filing this here so we don't forget about it. Might very well be a bug in the patch, but very hard to say.

While maybe the patch is not super nice, I doubt somehow that it's the source of this problem. The only thing that appears to get corrupted is one of the downstream server ports. Needs quite some time/traffic for this to show up.
