What should happen when mbufs/mbuf clusters are exhausted? Are packets dropped, does the kernel panic, or hang, or ...? Does RELENG_4 behave differently than RELENG_6 or HEAD when mbufs/clusters are exhausted? I know that 5.3 and later allocate and free mbufs/clusters dynamically, but are these newer versions more robust in the face of allocation failures? I thought I read once that they were, but I would like to make sure. Thanks in advance. Matt
