Hi!
Steven, this is the first thing that comes to mind when any application starts misbehaving on a Raspberry PI…
I already suggested it here
and now dicko does it as well…
You might want to backup and make screen captures of your current and working (at least it was) configuration…
If your requirements are modest you don’t need a powerful PC to run FreePBX. If it is important for you that your system be reliable I suggest you use the PI for something else and run FreePBX on a more conventional PC…
As I said earlier in other threads I do have Raspberry PI’s but I would never try to use them for FreePBX or anything that needs to be reliable…
Good luck and have a nice day!
Nick
