It's hard for children to introspect on and report their own busy status, and
there's no distributor/supervisor process that has that kind of awareness about the
children[1].
`ss -nl` (or `netstat` equivalent) will show you, in the RecvQ column, the number of
packets (UDP) or connections (TCP) that are stacked up and going unreplied by any child.
This figure should be 0 or substantially 0 if things are going well.

If TCP children are busy,
Please correct me if I am wrong if the remote IP is not responding via TCP protocol, this
leads to a timeout and this child is busy.
If many remote endpoints are not reachable via TCP this can lead to the case when half or
more children are by timeout operations.
I think required to monitor how many children are busy.
Is it possible to get such info using kamcmd utility, statistics module, or xprom
module.
