That is odd.

Please provide logs with debug enabled for HTTP/2 that cover the period 
from when the HTTP/2 connection was first established to the point where 
it is closed due to excessive overhead.

I can't judge about why there are so many of such frames.


The debug log will show the overhead changing for each frame so there should be
