| This is a bit of an epic, sorry. For a year or so we have had a system configured that after build triggers an ssh slave (14.04 LTS) in a test chamber to run hours of tests, an hour after a build, 12 hours overnight and 60 hours over the weekend. All stable and happy. For the last couple of months we have been recreating the setup for a new product, pretty much a copy/paste of the existing system except this is on 16.04 LTS. Here is the twist, adding the new system seems to have broken the old. I have about logs of about 600 good jobs up to 16th Feb, after that about 2 in 50 have worked. I cannot even work out which end is failing. Over the last weekend I disconnected Jenkins from the slaves (I changed the addresses not just offlined). On the jenkins server I ran 2 command windows, in the windows I ran ssh connections to the slaves and executed the commands manually to run 60 hour tests on both. Both stayed up for 60 hours and ran to conclusion. Tried automated again this morning, broken in minutes. I spotted this morning a new version of the ssh plugin, so I upgraded from 1.25.1 to 1.26, same results. Any ideas... The jenkins log looks like this
