Hello guys,

Is there's a way how to set requested amount of ram for koji builders?

I'd like to use it as Firefox builds fail recently due low memory, like
https://bugzilla.redhat.com/show_bug.cgi?id=2241690


I looked at the first linked build log in the ticket and it looks like the
build failed in the debuginfo extraction step. In that log, find-debuginfo
is called with -j3, and it could be that it ran out of memory because it
was trying to do 3 debuginfo extractions in parallel. You could try to
stick something like this in the spec file to tune it down:

# Require 32 GB of RAM per CPU core for debuginfo processing
%global _find_debuginfo_opts %limit_build -m 32768

Thanks for the idea, Kalev. I went ahead and applied this, and builds
for F38 and F39 succeeded. Let's hope it really helps and this wasn't
just luck!

Thanks Adam!
