Hi, Though we are still learning what workload results in the problem, it appears that even minimal I/O on the file system may cause the OS to crash. One pattern that we saw was 'mkdir'. There is a chance that the DR site was not yet impacted because no I/O workload has been run there. In that case, rolling back to the prior kernel level (one which has been tested before) may be advisable.

Is rollback advised? They will be running from DR site for a day in another week.
