SXT Kernel failures and reboots
Hi All, I have posted before about RBSXT reboots for no reason but nobody else seems to be having the issues. We found that upgrading to 3.41 firmware seemed to stabilise them for some time, but in the last couple of weeks they just started rebooting again for no reason, sometimes every 4 or 5 days even. Has anybody else come across this issue ? Netinstall isn't really a viable issue for the majority of them as they are of course up on masts and in production, I am looking for some way of trying to stabilise them if possible. They are currently running 6.40.8 or 6.40.9 and 3.41 firmware. Any thoughts would be appreciated apart from replacing them. Regards Paul
Hi Paul, We don't appear to have had any recent issues with our SXT units, and we have a fair few of them around the place. I'm probably suggesting something you've already investigated, but have you looked into the usual power related issues? PoE in particular can cause some hard to track down issues. Temperature changes can cause issues with PoE and internal components too. Weather (temperature changes) could explain the intermittent nature of the problem. Do you have the option of putting one on a desk and letting it run for a while in a more controlled environment to see if the problem persists?

Is the error in the log a Watchdog reboot? I have had some mysterious Watchdog reboots on WAPacs and HAPacs recently. They were just set up as CAPSMAN slaves so nothing complex. But this is on one site I have had many weird issues with - like no other site. I think it's located on an old burial ground.

Hi Jason, Yes it is a watchdog initiated reboot, I can't check the voltage on them as these SXT's don't have voltage monitoring :-( Error is "router was rebooted without proper shutdown by watchdog timer" These routers are pretty simple in config, they are running OSPF though but apart from that and a /30 on each side of them there is nothing else they are doing except routing traffic, and not even a lot of that really. It could be the same as what you are seeing, the reboots are totally random and the device is working perfectly fine before and after the reboot.
