Issue with camera / Webview

I am getting the following error in the logs and my camera is not showing up:

Proxy servlet failed to stream content: java.util.concurrent.RejectedExecutionException: Max requests per destination 1024 exceeded for HttpDestination

I’m using simple config:

 Frame label="Cameras" { 
 	Video url="http://192.168.1.11/snapshot.cgi?user=admin&pwd=" encoding="mjpeg"
 }

It works for a few minutes after starting openhab and then stops. Any ideas?
