Description

After the netty upgrade in OAK-6564, there's a recurring warning appearing in the server thread:

18:54:44.691 [main] WARN  io.netty.bootstrap.ServerBootstrap - Unknown channel option 'TCP_NODELAY' for channel '[id: 0xa64bc5c4]'

We need to see what's causing it (i.e. was that option removed in the latest version? if yes, is there a substitute/change needed?).
