Hi, we have setup a bridge with vether0 and run the standard dhcpd attached to vether0. After a short time of usage I noticed that the system is running out of mbuf clusters.
It looks like this setup is leaking mbuf's. Each bootp request which is forwarded via the bridge - vether0 to the dhcpd leaks one mbuf. If the dhcpd is *not* running, the leaking stops immediately. This occurs under 4.8 and current. I can reproduce this behavior on two systems. I was starring about 4 hours on the bridge / vether / udp_input code but can not find the leak. Any hints which functions/code should be inspected deeply to find the leak? - Joerg
