Tsz-wo Sze commented on RATIS-727:
----------------------------------

BTW, it is a joke that a server cannot handle 7 requests at the same time.  I 
believe we could call this a configuration problem -- the server should be run 
with a larger heap since each request has 16MB.

> Garbage collection due to same request retries on a follower

> In a heap dump it could be seen that a client request retries on the same 
> follower multiple times and every time the request is rejected with a 
> NotLeaderException. In case of Ozone it is a WriteChunk request which leads 
> to garbage collection of 16MB for every request. In the heap dump a client 
> request retries multiple times leading to garbage collection of ~100MB.
