VLAN's Showing but not running or even down.

This is really odd the past week or so randomly I have been getting a weird issue with VLAN’s dropping on CCR1016-12G r3 v7.11

whats happening is randomly it will drop some not always all vlans they are still present but not running there seems to be no log on the even other than devices dropping from the network as they loose there IP’s. I’m finding I’m having to login and disable and re-enable the vlans for them to come back up.

does anyone have any ideas? or is there anything else I can give you guys on figuring it out as it’s kinda stumbed me.

Downgrade or upgrade (testing version). 7.11 has serious VLAN issues.

Thank you bud any recommendations to drop to?

Either downgrade to v7.10.2 or disable fast path"

/interface bridge settings
set allow-fast-path=no
