A while ago we saw similar issues with
duplications, at least it was the same “Connection reset by peer” error
(although different error code).
It was fixed by changing our TCP keepalive
value on the media server. Perhaps someone changed a timeout value on the
firewall. Play with this value on the media server to see if it helps.

For windows, probably a registry change.

Connection time out (41)
Hey guys
I am receiving a Network Connection time out (41) on a
consistent basis when I run a backup on two of our servers. The servers are
behind a DMZ but I have set the BPCD connect-back to use the VNETD port and it worked
for a long time but now all I receive are 41 errors. The servers do write some
data but eventually error out. I am able to telnet to port 13724 on both
servers so there is no blocking on the firewall for that port. Any assistance
would be appreciated.
