I've just identified a bogon where at least the bn= xt driver can discard an incoming packet but still percolates a zero byte headerless packet to iflib that leaks an mbuf. If you can correlate packets discarded by the driver to the number of used mbufs you are probably suffer= ing from the same issue. I'll post a patch for iflib.c in a moment and I'm also opening a differential for it. --=20 You are receiving this mail because: You are the assignee for the bug.=
