I've got those logs. Unfortunately, hoping for more details. The logs do
show the test failure, but no details in failed-sshd.log indicating a
specific problem. Some of the formats are a bit wonky but I can live with
those. Since you mentioned NFS, which could have been constrained by UDP
packet sizes, and this platform sometimes cannot read beyond 56Kb off disk
(in some situations), it may be the read of regress/data that is failing.
Any pointers where that is hiding so that I can verify that data is actually
getting into sshd from the disk?

Cheers,
