Are those messages from Orion? Are you receiving any other log messages from the devices (i.e. syslog?). If not, I suggest enabling logging. They may contain more information about whats going on. If just Orion is reporting this, it's likely it is missing some pings or the AP is occasionally not available for pings. Do you see any common pattern to this (time between outages, length of downtime, etc.)?
Is that wireless interface / channel actually being used or is it just the management interface?
found it on a separate site.

Re: VLAN going down
The only thing that comes to mind:
If a VLAN is not assigned to a physical port (trunk or access), when users are not in that VLAN it is down. Type "show vlan status" to double-check what vlans are assigned to what ports. To keep that VLAN up without it being assigned to a physical port, use "operstate up" under the VLAN interface:
interface vlan 3022
