At some point, Box A started sending over 65Mbps of SIP OPTIONS packets to Box A. I do have qualify=yes for the peer on both sides, and the qualifyfreq is not set (aka default of 60secs).
Just because Box B was receiving 65MBps doesn’t mean box A was sending them. I suspect it’s probably the same one repeated, due to some kind of network problem. Do you have a pcap so you can look for the ID in the packets to see if they are the same? Would be good if you can prove A sent them too (traffic stats from SNMP monitoring or something).
