now i guess these files are the ones that control the server status page in the GUI, right? in which case, why is my Fcheck reporting that they were changed the other day? could this have been caused by a reboot?
Shouldn't be anything to do with rebooting... your services should stay static through a reboot.
Did you maybe enable/disable some service via the UI? That would add/remove files from that directory...
Does FCheck say exactly which one(s) were touched?
