Summit X450-48t suddenly reboots with Crit:Kern:Alert

[HarrySo]

In the last days i had a Problem with a suddenly reboot of one X450-48t Switch.

Is this a Problem with the Firmware? The Switch was running about 900 days without Problems. We are using the ExtremeXOS version 15.3.1.4 v1531b4-patch1-19.

Is an Upgrade required?

Thx for your Help

It's clearly indicate that snmpMaster process died. You may need to look for the know bug in that software.
Open TAC case, they will help you out in order to narrow down the issue.
