Service Watchdog Race Condition Possible?

[demux]

I have been running service watchdog without any problems for a long time now.
But now I would like to ask.

When restarting pfSense service watchdog comes up telling me that <1 to many> services are not running.
I understand this - the machine is coming up...
But it also says that it will restart all mentioned services.
Yes, I understand...

But is there a possibility that race conditions can occur if the same service is starting twice at the same time? (One instance by system start and one by service watchdog.)

The service watchdog package is not smart. It only knows to run on a timer from cron, and it only knows to see if a process is running or not.

So yes, race conditions are easily possible. Not just at boot but also during any deliberate stop/restart of a service, package ugprades, etc.
