Since firmware 4.7 i’m receiving complains from clients losing connection. I noticed that all clientes lose connection when the uptime on the device is around 80 days, the most recent case got exactly " 81 days, 7 hours, 7 minutes, 34 seconds" and then pppoe connection dropped, checking the AP and CnMaestro info, the signal was correct, the CPU use was stuck at 100% during one hour and then it completly stopped working. This is simmilar to all other CPE with this issue.
After PoE reboot on client side the connection is back online as usual, getting back the same signal levels as before the CPE stopped working.
This is happening in different BTS and phisical locations, the only thing that it’s same to every SM is that they are all in the same software version and we0ve been receiving the reports after the mass update to 4.7.0 version.
Release notes for version 4.7.0.1 don’t mention any fix related to this, the only way to prevent it seems to reboot the device before the uptime hits 80 days.
Any idea how to fix this issue? (besides me restarting every CPE from CnMaestro manually before the 80 day)
