Harrison our friendly neighbourhood underpaid host popped into chat tonight and confirmed something that Marquisite (Ryan) and I speculated on a while back. Multicast packets from people logged into the site and or chat are hitting the ACL host firewall and causing the crashes that we have been experiencing of late. If you are broadcasting multicast to your E1.31 devices and are logged into chat and/or the site there is every possibility you are contributing to crashing. If possible log out whilst you're testing or running your show. Multicast is easier but it throws packets here, there and everywhere.
