3850 switch stack rebooting

[pbuch]

I have a stack with 3 ws-C3850-48T switches.

They are running 3.3.4SE firmware.

Installed 12 sept this year.

Yesterdag the stack suddently rebootet.

To day they have just rebootet Again.

Are there a more stable version ?

Since these are 3850s, I am assuming you have service contract.  If yes, open a ticket with Cisco before upgrading the IOS as it can also be hardware related issue.
