The following reply was made to PR kern/28844; it has been noted by GNATS.

These all run half-duplex 100Mbps. (2) Furthermore, as netstat -m showed that the peak use of mbuf clusters (944) came awfully close to 1024 (default), NMBCLUSTERS=4096 was set. After a flawless operation from 4-sep-2001 on, it crashed again on oct-29 and oct-31 (the panic message is: page fault in kernel mode). This is not acceptable. Should we upgrade to 4.4? Go back to 4.0? Is there a special kernel param NO_PANIC which should be set to 1? I stress, this is not a test lab, it's a production environment. If FreeBSD is not suitable for this, please tell me.
