I am having issues with switches rebooting themselves. We've seen this for a long time, but a lot have been resolved after updating to 1.5.5. Now all reboots are consistently the same as per the log below. There's nothing to explain the cause other than the watchdog rebooted the switch. BTW this isn't a grounding issue!

I'm interested in this issue as we are also experiencing the same issues.

I asked Stephen to look at this for you.

Can you guys PM me your config's for the switch's that are having these issue's? Also before that if there are any passwords locking down the system please remove them first so I can access them. Then use Device->Backup to download the .ncfg file and send it to me.

Check free memory. If it going near to zero, the switch reboot itself.

Had another switch reboot. Here's the log. I'll PM the config.

Is there any news on this issue?

Thank you for the config's. Only news so far is that I am actively troubleshooting the problem right now. I may have some more questions as the situation develops and I'll ask them here.

Any updates on this?
