> [avro-ipc-netty] NioEventLoopGroup leak in NettyTransceiver
> -----------------------------------------------------------

> Reporter: Benjamin Leber
> Assignee: Benjamin Leber

>
> The NettyTransceiver is used on server and client side. While it requires a
> worker group on client side this is not necessary on server side.
> But as the worker group is initialized during the variable declaration. It is
> also created on the server for every new connection, but it gets never
> closed. This causes high off heap memory and always increasing open file
> descriptors.
> !image-2021-06-30-07-53-20-767.png!
> Moving the creation of the workger group into the constructor which is called
> on client side, solves the problem (deployed after the second 12:00 in above
> graph)
> I will provide a pr to fix.
