Hi,
From the error, you might be facing an issue with firmware communication between switches. The switches seems are not at the same firmware level. Usually when the switches are stacked, the firmware will propagate. But from that error, there is a communication issue. It did not indicate which switch though. Can you update the firmware to the latest.
What was the issue that it recovered by itself?

Hi Joey,
Thank you.
It seems that unit 1 experienced the issue, both switches are at the same level and the stack recovered itself in about 3 minutes.
1 6.5.4.20 6.3.0.18 6.5.4.20 6.5.4.20
2 6.5.4.20 6.3.0.18 6.5.4.20 6.5.4.20
I could schedule a maintenance window to update to 6.5.4.23, but I do not see any related changes in the changelog.

Hi,
the system's firmware is important being up to date newer version may include bug fixes for similar issues. You can also check SFP+ optics are properly seated and connected. You can check port configuration and set to correct mode.
