Hi, I am experiencing a problem on FreeBSD 4.9, yes I know this is ancient history but I am stuck with it for the time being, that exhibits itself as the ipintrq.ifq_len slowly growing until it finally reaches ipintrq.ifq_maxlen and the network stop responding because there is no place to put the incomming packets. If I console into the box and use sysctl and increase the maxlen things will again work until the new maxlen is reached. I know this is happening because I added a sysctl that would allow me to peak at the value of ipintrq.ifq_len. This only happens when I am running ospf and increase with activity. If someone could point towards where the multicast logic is I would appreciate or any other thoughts would be greatly appreciated. I have also posted this problem to the quagga devel mailing list and the fbsd-stable mailing list. If there is any other information that would be helpful I would be willing to supply it. Thanks in advance, Steve -- "They that give up essential liberty to obtain temporary safety, deserve neither liberty nor safety."
