Re: Flushing like mad

Hello.

Yes, it can happen, especially under high workload.
Also you may observe the warning: "search by key:
too many iterations", which has the similar nature.

If those warnings are sporadic, then simply ignore them.
We are not ready to get rid of them completely for now,
as in some cases it indicates data corruption (in this
case the warnings look like flood).

Thanks for report,
Edward.
