Description
Uploading files using the SCP plugin (version 1.3) sometimes fails with strange
exceptions (visible in the console output of the job, nothing to see in the
server's log).

The exceptions happen from time to time - leaving the build as "UNSTABLE".
Usually a rebuild fixes it.

We are having the same issue with SCP plugin 1.6 and Hudson v 1.355.
Here is the output from the console :

This turns all jobs into unstable. Possible workaround for this: do not set serverAliveInterval for the ssh connection.
I had problem with "SSH remote hosts" in jenkins config,
using plugin to ssh to remote host and execute commands reported "jsch.JSchException: session is down".
Clearing the ServerAliveInterval setting for some hosts in config solved the problem.
See this report, bug in java jsch:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=526867
"Can confirm, commenting out `ServerAliveInterval` does the trick. Thanks for investigating the issue!" - Julian Dax
please try it with latest version. If problem remains please provide stacktrace
