HTTP2 provides flow control options which allow you to limit the amount of data on flight. A client can send an increment for a window size to an initial value set by standard to 65,535 bytes. BIG-IP used 64K value inherited from SPDY, causing overflow when the client tried to increment the value to its maximum.
BIG-IP considers the window size overflow as a protocol violation thus it shuts the connection down not serving any request.
HTTP2 profile is configured on a virtual, and client sends a WINDOW_UPDATE frame to increment the value to its maximum.
None.
With a correct value for initial window size (for both a connection and a stream) BIG-IP correctly processes an increment request of the window size to its maximum.
