Huge Numbers of Illegal Requests

On 2 different OpenIndiana 151a7 systems, Im showing a huge number of
Illegal Requests.  There are no other apparent issues, performance is fine,
etc,etc.
Everything works great - what are these illegal requests?  My Google-Foo is
failing me...

Thanks,

-ed

My system used to exhibit this problem so I opened Illumos issue 2998 
(https://www.illumos.org/issues/2998).  The weird thing is that the 
problem went away and has not returned.
