We are having the EXACT same issue as Mark above - it's completely and totally intermittent. Has there been any progress in getting a build that fixes this issue introduced by Oracle releasing u121 that supposedly fixes soemthing broken in u112 that apparently JSch 0.1.54 was depending on that now introduces a completely random and intermittent failure now? I REALLY do not have the bandwidth to swap out for a new SSH Java lib, so if there is a build coming, could someone please let us know? Thanks...
