------------------------------------

Hi [~phoenixjiangnan],
no, the error you are seeing is not related to the network code but rather to timers and state.

> Currently, we have our own {{Buffer}} class backed by a {{MemorySegment}} and whenever
we try to write to or read from Netty, we need to copy to / from Netty's {{ByteBuf}} instances.
> This is am umbrella task for avoiding these buffer copies and some related code changes
