Hi,
adding some information...

sometimes I get this on my SUN Fire v440 when there is some traffic:
cas0: status=7889090<RXDONE,RX_COMP_FULL,RXMAC>
cas0 stops working then. Using "ifconfig cas0 down/up" only helps for a
very short time. Only way to get it to work again for some time is a
full reboot.
Played a bit around and noticed that this only happens when increasing
net.inet.tcp.sendspace and/or net.inet.tcp.recvspace.
Increasing net.inet.tcp.sendspace is suggested by dhartmei@ inside his
undeadly.org CGI scripts.

Changing those values works just fine on all other systems I am running
OpenBSD on with vr, sis, bnx, bge, em and ral interfaces, just not with cas.
So, bug in the cas driver?
