httpd.service uses 'Type=notify'
Type=
Configures the process start-up type for this service unit. One of simple,
forking, oneshot, dbus, notify or idle.
Behavior of notify is similar to simple; however, it is expected that the
daemon sends a notification message via sd_notify(3) or an equivalent call when
it has finished starting up. systemd will proceed with starting follow-up units
after this notification message has been sent. If this option is used,
NotifyAccess= (see below) should be set to open access to the notification
socket provided by systemd. If NotifyAccess= is not set, it will be implicitly
set to main.
If set to simple (the default value if neither Type= nor BusName= are
specified), it is expected that the process configured with ExecStart= is the
main process of the service. In this mode, if the process offers functionality
to other processes on the system, its communication channels should be
installed before the daemon is started up (e.g. sockets set up by systemd, via
socket activation), as systemd will immediately proceed starting follow-up
units.
Looking at the code, the message seems to be an older version of this:
./src/core/service.c-2553- if (s->notify_access == NOTIFY_MAIN && pid !=
s->main_pid) {
./src/core/service.c-2554- if (s->main_pid != 0)
./src/core/service.c:2555: log_warning_unit(u->id, "%s:
Got notification message from PID "PID_FMT", but reception only permitted for
main PID "PID_FMT, u->id, pid, s->main_pid);
So rephrasing:
Got notification message from httpd, but reception only permitted for
pacemakerd
So it seems that systemd is calculating the wrong value for main_pid
