Hi folks,

A heads up for folks running GPFS on RHEL7.6 (and I guess derivatives) 
from a colleague on the Australian HPC Slack:


"IBM has identified an issue in IBM Spectrum Scale (GPFS) version that 
support RHEL7.6 ( or later and or later), in which a 
RHEL7.6 node running kernel versions 3.10.0-957.19.1 or higher, 
including 3.10.0-957.21.2, may encounter a kernel crash while running an 
IO operations."

Basically it looks like they've fallen foul of this hardening fix:


All the best,
