Hi All,

First of all I want to thank you for your product. We use it a lot in
different forms in our data centers across the world.
Iｹm running into a strange issue with our ftp-sftp proxy. If weｹre
transferring larger files then 10 mb, 10485760 bytes to be exact, we get
disconnected from our session with the error ｳnetout: Connection reset by
peerｲ. See below. Maybe you can point us in the right direction.

Tried it with dg version 9.9.5 and 9.9.7
