[Beowulf] SIMD exception kernel panic on Skylake-EP triggered by OpenFOAM?

Hi folks,
We've had 2 different nodes crash over the past few days with kernel
panics triggered by (what is recorded as) a "simd exception" (console
messages below). In both cases the triggering application is given as
the same binary, a user application built against OpenFOAM v16.06.
This doesn't happen every time, I can see about 28 successful runs of
the application this month (the binary was built at the end of August).
The system in question has 2 x 16C Xeon Gold 6140 Skylake-EP CPUs.
Any ideas?
