Hello
I apply the new patch and it looks good, no "long lost child" in log
after graceful.
Best regards

Hi!
I have finally reproduced the "long lost child" messages on my
development machine and made a fix for it. First of all, these
messages were silently ignored by the server if no graceful restart
had been made on the server. The patch below also removes this
restriction, so it would report these children in any state.
These messages were logged if a kill signal was sent to a processor,
but before the child could exit, the multiplexer would try to revive
the child (multiplexer always keeps the processor child alive, if the
vhost is active), which would create a new child in the slot and thus
making the previous processor gone from the scoreboard. No other harm
was done except the log messages because the previous processor was
shutting down anyway. Potential improvement here may be to not kill
the processor if the vhost has active workers or make the multiplexer
activate the processor only if the server environment has no workers
alive.
The patch is located here:

(should apply to both v13 and v15)
