Stops accepting connections after a time. #19
Description
We have a VERY simple ftp server that is based on the MemDriver example. All the server is trying to do is accept PUTs from an authorized user and then putting the content of that file onto a RabbitMQ. It seems to do perfectly at first and then over time (and after a lot of people/bots trying to poke it) it will get to the point that it wont accept any connects and doesn't out put anything to the terminal until I hit a key and then all at once the terminal is filled with the log below
For context the server name is "customFTP to RabbitMQ":

Would love to hear any ideas! Happy to add more info on request, but I checked and we seem to be handling all the Close() calls for the various connections and the rest of the system seems stable, so I don't think it's a memory leak. For other context this is running on a windows server, not sure if that makes a difference! Thanks!
