Hardware is Ok: it can build world 10 time in loop with 8 jobs (-j8) and MAKEOBJDIRPREFIX set to non-/usr filesystem.
When MAKEOBJDIRPREFIX is empty (is not set) every third build is failed with this error.
/usr filesystem is clean and HDD with it is in good condition.
Here are wnought space on /usr (about 250Gb) and /tmp (450Mb).

Re-run `buildworld' with -DNO_CELAN typically finish build after that.

>How-To-Repeat:

Build world several times with default (not set) MAKEOBJDIRPREFIX
