Hi,
Please check for sh processes cpu sorted for higly utilized event.
Also please check for sh interface counters nonzero if there is any particular user who is creating huge traffic / loops which is causing the cpu process to go down.
Also check in sh logging to find any port which makes continious violation.
I hope with this you can sort out the problem.
Also you need to have a proper Qos if you much priority traffic to go out without any issue.
Please do rate if the given information helps.

Here is a list of reason why a multicast packet would be punted to the CPU:
I often see TTL set to 1 as the most common condition.
You mentioned you enabled multicast on all Vlans, can you provide the configuration from the switch along with the output from 'show ip mroute' ?
