I have a series of files I need to copy via SCP over a VPN to a remote linux server each night. The files are not large, we're talking about tens of megabytes here, but the file copy almost always stalls after a few seconds. Running the SCP command with -vvv, I see the following over and over throughout the attempted copy process:

debug2: channel 0: rcvd adjust 131072
debug2: channel 0: rcvd adjust 131072
debug2: channel 0: rcvd adjust 131072

Any thoughts? I see this question being asked in various places out there, but never any answers. Any help would be appreciated.
