I believe @jmorris is currently out of the office, I think he’s going to be back next week.
I’d also recommend looking at your network topology. The error you’re getting looks like the TCP connection was closed while in progress. This could have been done by the server, but it also could have been done somewhere in the network stack on the server or by the network infrastructure. Perhaps a maximum TCP session time or a short TCP inactivity timer somewhere along the line.
