Open Radar

 
Hi All,

When we hit play on our client to play HLS, we get the log below. Afterwards when we try other clients like safari and youtube we are getting the same log. This continues until we restart the device. After reboot everything is working fine.

What might be causing the problem and how can we solve it? Thanks.

Device is iPad 9.1 (13B143) and has free storage of 11.2 GB
