Ok, I've taken a look at the build log. A while ago I inserted a "spy" line in debian/rules so that we could see this in the build log:
=========================== MemAvailable: 7472456 kB SwapFree: 0 kB nproc: 2 =========================== So, yes, this will not work in Salsa CI, unless there is a lot of swap. Simple questions: Do all Salsa CI runners have the same amount of RAM? Do all Salsa CI runners have zero amount of swap? (Why?) (While we are at it: What should people do when a package needs more than 8 GB of RAM to build? I could provide a list of such packages, as I collect statistics during my archive rebuilds). Thanks.
