Fluss version

0.5.0

Minimal reproduce step

Sends unlimited requests to the server and the server will put all of them to the request queue...

What doesn't meet your expectations?

Although configure netty.server.max-queued-requests is 500, the server will still put unlimited(much more than 500) requests to the request queue which will cause the server to run out of the memory and can never restore...
In my env, the server will throw unlimited exceptions:

Caused by: com.alibaba.fluss.exception.UnknownServerException: java.lang.OutOfMemoryError: Cannot reserve 4194304 bytes of direct buffer memory (allocated: 32175177900, limit: 32178700288)

And the request queue is filled with ~25 k requests.

Anything else?
