I am not shocked that my previous message may have been removed. There is a bit
of brute science involved as well. A false burst may seem to tune a network. A
properly timed burst is more effective in gaining authorization. You don't need
magic code to leverage a network you just need to generate request that is
swifter to answer than drop.
Your own configurations can be to blame. Suppose you require a percentage of
answered to blocked requests. You open that door.
Suppose you want a specific set up time, whatever it is the shorter the better.
When those connections go underutilized you may have a smoking gun.
Any fans of NPTEL? A lecture I watched today was quite synchronised.
Earlier I should have written so NOT do this...
You would also be looking for many many symlinks for users who exploit the
network itself, I am on!y trying to help and don't know for a fact or do any of
these sorts of things.

Oh yes, this is why I wanted to bring it to everyones attention, this
isn't just about Lustre, it's much more widespread.

As Kilian wrote in the Lustre bug quoting his RHEL bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1618452
— Comment #3 from Don Dutile <ddut...@redhat.com> —
Already reported and being actively fixed.
Cannot make this public, as the patch that caused it was due to
embargo'd
security fix.
This issue has highest priority for resolution.
Revert to 3.10.0-862.11.5.el7 in the mean time.
This bug has been marked as a duplicate of bug 1616346
