I am seeing errors reported by "netstat -i". I am running a 7.2 kernel. delta88b% netstat -i Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll eth1 1500 00:a0:98:08:6c:ef 17515937 114620 12317753 0 0 eth1 1500 192.168.10.0 192.168.10.8 17514886 - 12317738 - - How do I find out why there are these errors? I see that there are enough mbufs, and though there are mbuf failures reported, the Ierrs are significantly higher. delta88b% netstat -m 6441/26064/32505 mbufs in use (current/cache/total) 5792/250208/256000/256000 mbuf clusters in use (current/cache/total/max) 5124/955 mbuf+clusters out of packet secondary zone in use (current/cache) 128/336/464/12800 4k (page size) jumbo clusters in use (current/cache/total/max) 512/283/795/6400 9k jumbo clusters in use (current/cache/total/max) 0/0/0/3200 16k jumbo clusters in use (current/cache/total/max) 18314K/510823K/529137K bytes allocated to network (current/cache/total) 0/3485/1350 requests for mbufs denied (mbufs/clusters/mbuf+clusters) 0/0/0 requests for jumbo clusters denied (4k/9k/16k) 0/0/0 sfbufs in use (current/peak/max) 0 requests for sfbufs denied 0 requests for sfbufs delayed 0 requests for I/O initiated by sendfile 0 calls to protocol drain routines Any help is appreciated. -vijay
