Hi Brian,
OK, seems to me that it's have responses that are bunching up. Did you turn
on the rate limiting? If so, what is the "cms.dfs" directive look like?
Andy
P.S I will soon remove the offending code that you pointed out.

One server is below (*). However, I don't know if the log message occurs
when it gets the query, or when it responds to the query.

I also included below when the selects were performed. I don't know the
best logging line to look for, so I included two different views.
I should mention: these servers are running the latest git sources; they
ought to include the late limiting code. The manager is running a release
prior to 3.0.0; just upgraded that to the latest pre-release, which is how I
found the bug in the other email.
