Hello,
In our company, we have two Cisco CBS350-16XTS devices configured in a stack. For some time now, we've been experiencing issues with one of the units.
A month ago, the first failure occurred with Unit 1, which was acting as the master. The logs only showed information related to a critical system error.
Logs:

After restarting, Unit 1 functioned normally for a month. However, it recently failed again, and this time it started rebooting in a loop.

Could you please advise on how we can resolve the issue with Unit 1 in our stack?
