We ran into this as well. In our case the two daemons are:

/opt/exim/bin/exim -bd -q5m
/opt/exim/bin/exim -q1m -Rr [@.]cam.ac.uk$ -oP
/spool/exim/exim-q-hermes.pid

The second daemon forces frequent retries for local email (1m rather
than 5m) to stop a backlog forming if a local mail system is down for a
short period of time.

daemon_notifier_socket() seems to be new in 4.94: it wasn't there in
4.92.3

Ultimately the paniclog entries seem to be harmless and I can ignore
them (or use -oX), but this is a separate use case for multiple daemons.
