Description

SSH sessions into Karaf are aborted after about ten minutes of inactivity. The following message is written to the log:

14:35:26.042 WARN [sshd-SshServer[616ddc]-nio2-thread-2] exceptionCaught(ServerSessionImpl[karaf@/127.0.0.1:40676])[state=Opened] InterruptedByTimeoutException: null

The problem started some weeks ago with the Karaf version shipped with openHAB, it's currently on 4.1.2. I've also tried a plain Karaf container though (version 4.2.0.M1) and get the exact same problem there. This has been discussed in the openHAB forum here: https://community.openhab.org/t/timeout-in-karaf-console/35443
