Before it started to fail I was using single-CPU machines with only
1 GB of RAM and 1 GB of swap, and this was enough.

One might think this is ridiculously low to build Debian packages in
general, but it's in fact enough to build 96% of all source packages.

After the failures I retried in machines with only 3.75 GB of RAM
and 3 GB of swap and then it worked again, but in some cases I've seen
the build process to allocate up to 9 GB of RAM. I think this is
just memory overcommiting on the side of MariaDB, the usual victim
of OOM killer in small Wordpress installs not having enough swap.

Thanks.
