I had some of these too, until I explicitly set this named option: tcp-listen-queue 20; Looks like the default is 10. The way I interpret this parameter is that this sets the *operating system* listen queue, i.e. the backlog argument for the listen() system call. After changing this to 20, I had no more of the "quota reached" log messages. Platform: FreeBSD 12.1 on 64 bit Intel.
