SG350XG-2F10 stack sudden reboot

[vormetla@gmail.com]

Hi. I've got hybrid stack of 4 switches

1 SG350XG-2F10
2 SG350XG-2F10
3 SG350X-48
4 SG350X-48

Sometimes (approx. once a month)  master unit goes to reboot, then backup unit becomes a master and reboots too. Slaves don't reboot. All units are powered from UPSs (master and backup from different one). Enviroment is OK (+19C air conditioned room). Software Version: 2.5.0.79 

sh log file shows this:

Hi,

Please disable smartport and configure VOICE VLAN manually.

Data VLAN and Voice VLAN should not be the same.

If still facing an issue, please open a new case with us by calling frontline support team, so that we can troubleshoot the issue further :

Please mark this as helpful if it resolves your query.

Thanks, riteshsh!

I've changed Voice vlan id and disabled it. Also disabled smartport on each interface.

Switch#show voice vlan
Administrate Voice VLAN state is disabled
Operational Voice VLAN state is disabled
Best Local Voice VLAN-ID is 666
Best Local VPT is 5 (default)
Best Local DSCP is 46 (default)
The Operational Voice VLAN-ID is 666
Aging timeout: 1440 minutes
CoS: 6
Remark: No
Switch#show macro auto ports
SmartPort is Enabled
Administrative Globally Auto SmartPort is disabled
Operational Globally Auto SmartPort is disabled

Interface Auto SmartPort Persistent SmartPort Type
Admin State State
----------- ----------------- ----------- -------------------------------
te1/0/1 disabled disabled default
te1/0/2 disabled disabled default
te1/0/3 disabled disabled default

.....

However, it says Smartport is Enabled. Can't find how to disable it.

UNfortunately, disabling smart port didn't help. I've also upgraded software.
