https://bugs.exim.org/show_bug.cgi?id=3046

--- Comment #7 from Wolfgang Breyha <wbreyha@???> ---
after our talk on IRC about daemon.c:~2780ff
sigalrm_seen = daemon_notification();

I tried to figure out what is different in 4.97 compared to 4.96 which never
stopped running the queue.

And I found this new event
NOTIFY_REGEX
which is triggered by regex_must_compile() and used a lot IMO at connection
startup.

Receiving this event will also return FALSE for daemon_notification() and clear
sigalrm_seen.

The second patch in this bugreport changes this by not overwriting
sigalrm_seen, but it does not add any debug log output. Maybe that's the cause
why we do not see a clear indication for the now working queue runners?

I'm currently running another patch which logs a line if sigarlm_seen = TRUE
and the return code of daemon_notification() is FALSE. Let's see if it confirms
the suspicion.
