Who Me Too'd this topic

Hello, 

since a few weeks, we are notice a lot of timeouts in our network. We figured out that there are unplanned reboots in our stack. This is what the stack is logging: 

We are using the stack in a ring-topology in hybrid-mode with the firmware 2.5.5.47 and the following models: 

- SG550XG-8F8T
- SG550X-24MP
- SG550X-24
- SG550X-24

Is there any way to figure out why the unit was rebooted? Do you need any other informations? 

Thanks in advance.
