BTDT. It was unusable. People can search the list archives if they're interested in
details. At this point, I can't even get in:

This error indicates that you are running out of process quota on the
bastion server due to the number of processes that you are attempting
to run in parallel. We have fairly strict limits placed on each user
to help prevent overwhelming the bastions. The quota is typically
enough to run 2-3 small applications.
I can see that you are currently logged into the
dev.toolforge.org
bastion (tools-sgebastion-08.tools.eqiad.wmflabs) where you have a
tmux session running with four bash shells and a python process that
appears to be some sort of TCP log event sync. This last process is
almost certainly pushing your thread quota to the limit.
I understand that k8s is scalable, and the way of the
future, and that upgrades need to be prioritized, etc. But the current setup is not an
effective development environment.
This may actually be the root of some of your frustrations. Toolforge
is not meant to be a replacement for a development environment on your
local laptop or other server. It is intended primarily to be a runtime
environment for tools. Attempting to use the bastions as your primary
development environment is going to be a struggle against the various
quotas and limits that have been placed on the bastions in an attempt
to keep them available and responsive for people who need to
start/stop/restart their tools and check log output.
You might be interested in things like

to help you find a way to develop and test your software outside of
Toolforge.
