I only went quickly over the thread and that on a phone. So I have not full
insight. But a few notes:

See
https://www.rsyslog.com/doc/v8-stable/configuration/modules/impstats.html
it has a description of the counters, search for oubound and do as
suggested.

If we have stalled input (and also in most other cases) a debug log should
help diagnose.

Sent from phone, thus brief.
