After installing some new PMP450s we had an issue where they would spontaneously reboot when you would try to access their web interface. We managed to narrow it down to the "Webpage auto update" setting. Whenever it would reach the time specified in that field, the PMP (either AP or SM) would reboot.
We fixed this by changing the value to 0, so they never auto update, and we dont have this problem anymore.
This was using 13.2.1, so a pretty old firmware, but I searched this issue and couldn't find any results anywhere on the internet about it, so I thought it might help out someone in the same situation one day.
Anyone else experienced this before? Feel free to delete this thread if there is an old one that I couldn't find.
Also saw some unresolved reboot issues threads around the place that could perhaps be attributed to this issue, but had not been aware of this fault. Good to share possible causes...
