Co:Z V2.4.5, Z/OS 1.13
Receiving this in my z/OS Co:Z batch job log sending a file to a client's Linux server.
Received disconnect from xxx.xxx.xxx.xxx: 2: Packet corrupt
General Google searches seem to indicate this is some kind of issue with a network adapter, checksums, etc. Is there a good way to shoot these issues to find a root cause ?

Re: Received disconnect from xxx.xxx.xxx.xxx: 2: Packet corrupt
These errors indicate that the remote SSH server detected that it received a corrupted SSH packet. The remote server sent an SSH "DISCONNECT" packet back to the z/OS OpenSSH client and then disconnected the socket.
This error indicates that there is some kind of network error (firewall, bad adapter, etc) that is corrupting data.
I can't recommend any specific tools for diagnosing a network problem, but you would probably need to get a network engineer to diagnose it.
