As you've not mentioned any attempt to use the forum search engine or the knowledgebase for previous discussions of this error, can I recommend you try exactly that, and maybe starting with this "hit" where a number of technotes are referenced:

Also, if you are multicasting, but have failed to set up IGMP snooping on your switches, then the failure after a few minutes is due to this lack.
