Is there any way to bump up swap on the builders? Or any trick to get
more memory or run on a particular machine that has more memory?
The ARM builders (both ARMv7 and aarch64) have 24 Gb of memory, which
is more than all other arches which have 10Gb, so I suspect the issue
is not in the build hardware but an issue with ceph itself using (or
leaking) too much memory.
Strangely the error message is complaining about being unable to
allocate 10 MB, with a current total usage of 55 MB, so no where
near the GB of memory, unless there is some other process running
in parallel which is consuming it all.
Regards,
Daniel
It looks like the whole parallelized make-process is hitting the 4
Gbytes limit per process / task on 32 Bit arches…
Have you tried this?
%build
export CFLAGS="echo %{optflags} | sed -e 's!-pipe!!g'"
export CXXFLAGS="$CFLAGS"
…
Sometimes piping from cpp to gcc to as to ld takes too much memory on 32
Bit arches…
Cheers,
Björn
