There are many ways for a buildworld to fail and you have
given no clue what way yours did via, say, showing any of
the messages about the failure(s) involved.

Did any of the following types of messages show up on the
console (or in related logs):

> pid . . .(?), jid . . ., uid . . ., was killed: failed to reclaim memory
> pid . . .(?), jid . . ., uid . . ., was killed: a thread waited too long to allocate a page
> pid . . .(?), jid . . ., uid . . ., was killed: out of swap space

If yes, which?

How about the following messages (which, of themselves to not
indicate any process has been kiled):

> swap_pager: out of swap space
> swp_pager_getswapspace(. . .): failed

Are you using something like ( in, say, /boot/loader/conf ):

#
# Delay when persistent low free RAM leads to
# Out Of Memory killing of processes:
vm.pageout_oom_seq=120

This delays potential "killed: failed to reclaim memory" kills,
possibly long enough to reach a state where sufficient memory is
reclaimed.

I'll note that the status "killed: failed to reclaim memory" does
not require that swap be used much at all. Sustained low free RAM
from just one process that always stays runnable can be sufficient
to end up with such kills. Thus, SWAP need not be relevant.

If you did not get messages such as the above, what was reported
about the failure?

I'll note that ZFS use and ZFS configuration can be important to
the memory usage. So can tmpfs use (which is covered by RAM+SWAP).
You may have other unreported competition for memory. But it is
not clear if there is evidence of a RAM or memory usage related
problem.

I'm going to stop trying to guess more alternative failures that
you might have run into.


Note:

In another message that did not quote from the message
I'm replying to here, you wrote:

QUOTE
I have 32GB RAM and 100GB swap, If -j should work problem is somewhere
else, will investigate, thanks :-)
END QUOTE

Having such information together in one message makes things
easier to find, even if one ends up quoting material from
past messages in order to make the related information easier
to find.
