I narrowed this bug down to the following patch to djb's ucspi-tcp (adds ipv6 functionality): http://www.fefe.de/ucspi/ I don't think that userland processes should be able to wreak that much havoc on the network stack. Another thing of note is that even if I kill the processes causing the problem, the mbufs are never reclaimed. Seems like a permanent leak. When I got rid of the ipv6 patch, the mbufs stopped building up and everything has been fine.. Note that the ipv6 traffic for this process was fairly minimal.home | help
