Nothing to do with but sparked by the Apache problem ...
One of the emails mentioned that the "ExecStop" section didn't appear to be working ... That's caused me considerable grief in a systemd config file I've written ...
Basically, somebody else added an ExecStop section - and all hell broke loose. It seemed to be firing on boot :-( And the service in question - ScarletDME - seemed to be killing processes at random, like DoveCot ...
Okay, accidentally killing processes it shouldn't is probably down the fork/exec code in ScarletDME, I haven't dug into it to know, but systemd should not be triggering the stop in the first place. Has anybody else encountered anything like this?
Sorry I'm not likely to respond quickly to say "solved", as I need to get "in the mood" to get back to debugging, but if anybody has any hints and tips, they'd be appreciated, and it might shed some light on that Apache problem :-)
Cheers, Wol
