juju ssh spawns many juju and ssh processes

[Jay R. Wren]

juju version 2.0-beta5-xenial-amd64 built now from master 601c5c17e8776573541618697dd9afa73e9e1c96

I built from master because previous master build (sorry i don't know hash) labeled 2.0-beta4-xenial-amd64 but before the release had the same behavior.

I deploy a charm and try to ssh to the unit:
$ juju --debug ssh blues-identity/0

Upon this pause, I ctrl-z to suspend the process and look at running processes:

[Anastasia (anastasia-macmood)]

I cannot reproduce this with Juju 2.1 tip and lxd 2.4.1. I see a stable number processes.

I suspect that the issue has been addressed.

Feel free to re-open if you are still seeing an issue.

[Jay R. Wren (evarlast)]

AFAIK, i've no observed this in a long time, it must have been a fluke or a 2.0 beta bug. Closing.
