My server recently stopped responding. It worked fine after a reboot and the only clue I can find in the logs is this:

Code:
[kernel] PAX: size overflow detected in function bdi_min_pause.isra.20 mm/page-writeback.c:1233 cicus.734_346 max, count: 29


Any ideas? I'm on 3.13.10-hardened.

mm/page-writeback.c: fix divide by zero in pos_ratio_polynom

related ?

at least this applies to 3.14, might also be applicable to 3.13

You probably nailed it, thank you.
