Software packet buffer depletion

I am working with a client who is experiencing very high CPU utilization on the data plane and his packet buffers do not release.  He is running 8.1.7 in a lab setting with no traffic being generated to the firewall.  He has VM is setup with 6.5GB ram and 2 cores, 1 for management and 1 for data plane, and 60GB hard drive with VM-100 license.

Re: Software packet buffer depletion

I should also add that about 2/3rds of the current traffic on the firewall is IPv6 multicast, if that is relevant.  Thanks.
