It's new for me that a FG muste be restartet when they runs for xxx days.
My last 100A runs over years and the only one i must reboot was when i updated the firmware.
All of them starts up gracefully.
Ok, the only thing is possible when a firmware was buggy.
But for me nothing else is known.
Does the Fg are in a HA-Cluster?
How do they restart the FG? (execute reboot ?)
