It would be really useful if you could elaborate on how pfiles screwed up your daemons. Though pfiles will stop a process to get its information, it does so for a very short period of time and in a fashion that should be undetectable to the target process. Unless a process has real-time scheduling constraints, it shouldn't be possible for it to tell that pfiles has stopped it. If you are seeing some problem where processes are malfunctioning because of pfiles, it is bug in pfiles that needs to be fixed.
