Bonjour Gateway - Airplay / AirServer - Random Disconnects

I am experiencing random disconnects during an Airplay session to AirServer. Airserver disappears from the screen and Airplay session is gone. Here is the details of my setup:

WLC 5508 7.5.102.0

1142n APs

AirServer (1.9.4) installed on wired PCs.

Wireless clients (iOS Devices 7.x and 6.x) use Airplay to mirror to the PCs running AirServer.

APs are in mDNS mode and snooping the vlan the PCs reside in.

Wireless clients in separate BYOD WLAN.

Enabled bonjour gateway and mDNS AP (trunk mode)

http://www.cisco.com/en/US/docs/wireless/technology/bonjour/7.5/Bonjour_Gateway_Phase-2_WLC_software_release_7.5.html#wp44311

Enabled videostream

http://www.cisco.com/en/US/products/ps10315/products_tech_note09186a0080b6e11e.shtml

Verified via packet capture the client traffic is being marked for QoS (and Gold enabled on BYOD WLAN)

Differentiated Services Field: 0x80 (DSCP 0x20: Class Selector 4; ECN: 0x00:  Not-ECT (Not ECN-Capable Transport))

This is an intermittent issue. I can play a YouTube video for 60 mins with no issues sometimes. Sometimes the disconnect happens. WLC mdns error debug output does not look significantly different when the crash happens.

Any thoughts? Similar experience?
