hello,
tmpfs is already disabled in poudriere.conf:
USE_TMPFS=no
a couple of people suggested changing PARALLEL_JOBS or similar settings.
i'm still trying to find the best combination of PARALLEL_JOBS and
MAKE_JOBS_NUMBER, but what's confusing me here is that system is
claiming out of memory while having plenty of free memory - so it
doesn't seem that too many PARALLEL_JOBS is eating the memory.
in the mean time i've added 16GB of extra swap (previously it had 2GB),
and this seems to have fixed the errors, but i'm not sure why this is
necessary.
Mem: 2440M Active, 18G Inact, 1696M Laundry, 8580M Wired, 1565M Buf, 1143M Free
ARC: 1959M Total, 548M MFU, 371M MRU, 22M Anon, 29M Header, 987M Other
404M Compressed, 1439M Uncompressed, 3.56:1 Ratio
Swap: 18G Total, 3090M Used, 15G Free, 16% Inuse
thanks, lexi.
