deploy gets stuck and doesn't print anything

[anyelopetit]

Steps to reproduce

cap production deploy
and that's it, just gets stuck forever until I abort it

Expected behavior

• Continue with deploying
• It must to print a TimeOut error log or something else

Actual behavior

When I run: cap production deploy it shows nothing, just keeps waiting
But when I run: cap production deploy --trace it shows this:

** Invoke production (first_time)
** Execute production
** Invoke load:defaults (first_time)
** Execute load:defaults
** Invoke rbenv:validate (first_time)
** Execute rbenv:validate

I'm getting this with airbrake 11.0.3 and 12.0.0. Airbrake 11.0.2 works fine.

If you do cap staging rbenv:validate --trace I see that
.rbenv/versions/2.7.4/lib/ruby/gems/2.7.0/gems/airbrake-11.0.3/lib/airbrake/rake.rb:17 and
.rbenv/versions/2.7.4/lib/ruby/gems/2.7.0/gems/airbrussh-1.4.0/lib/airbrussh/rake/context.rb:61 call execute back and forth until there's a Stack Too Deep error.

Have you found a solution?

Everything usually works fine, however today the deploy got stuck, without printing anything, until I aborted manually...

$ bundle exec cap production deploy
^C(Backtrace restricted to imported tasks)
cap aborted!
Interrupt: 

Tasks: TOP => rbenv:validate
(See full trace by running task with --trace)

Ok in my case it was a problem with ssh.

The server was completely stuck (it had constant linear high cpu after a system reboot after an os update).

If I tried to connect to the server simply with ssh I got connection timeout.

That was the reason for the blank screen on cap deploy.
