-------------------------------------------------------------------------
I am going to add also a thread dump printing.
Based on the source code the most suspicious place is this:
{code:java}
cfs.dumpMemtable(); {code}
It is actually async method which returns Future and highly probably we do not
have a backpressure here.
But it is better to see it from the diagnostic printing.
