[KARAF-7174] log:tail threads keep running after ssh exits

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 4.3.2
• Component/s: karaf

Environment

Ubuntu 20.04.2 LTS

Clean out-of-the-box Karaf 4.3.2 distribution

• Target Version/s: 4.5.0, 4.4.7

Description

When executing log:tail via Karaf's ssh connection, the created thread is not killed when the ssh connection is killed or timeouts.

I believe that all threads launched via ssh should be killed if the session is no longer active.

Steps to reproduce:

• Open a ssh connection with Karaf
• Run log:tail
• Either close the session without exiting log:tail or wait until it timeouts in a few minutes;
• Run shell:threads | grep log:tail on the console or another ssh connection
• A log tail thread should still be running.

Every time this process is repeated, a new log:tail thread will appear and stay alive.

I've attached the return of one of my shell:thread commands.
