You're saying that the server can take over a minute to start up and
this is considered acceptable?

What configuration is the other world build running with? I'd suggest
the system is so overloaded it isn't useful any more and you should
have pressure control enabled or other mechanisms to allow the system
to function.

I'm not keen to make this any more configurable as 60s should be enough
and if it isn't, there are different issues at play.

Having bitbake silently hang for minutes at a time isn't good for users
and isn't good for CI either.

Cheers,

Richard
