I bumped kern.ipc.nmbclusters by a factor of 100 (from 2036224 to 203622400). As Hiren said, kern.ipc.nmbufs auto-adjusted (from 13031835 to 205111860). However, I still see "requests for mbufs denied" immediately after reboot. root@laurel:~ # netstat -m 12280/1580/13860 mbufs in use (current/cache/total) 12279/827/13106/203622400 mbuf clusters in use (current/cache/total/max) 12279/819 mbuf+clusters out of packet secondary zone in use (current/cache) 0/3/3/1018111 4k (page size) jumbo clusters in use (current/cache/total/max) 0/0/0/301662 9k jumbo clusters in use (current/cache/total/max) 0/0/0/169685 16k jumbo clusters in use (current/cache/total/max) 27628K/2061K/29689K bytes allocated to network (current/cache/total) 253/5481/12473 requests for mbufs denied (mbufs/clusters/mbuf+clusters) 0/0/0 requests for mbufs delayed (mbufs/clusters/mbuf+clusters) 0/0/0 requests for jumbo clusters delayed (4k/9k/16k) 0/0/0 requests for jumbo clusters denied (4k/9k/16k) 0 requests for sfbufs denied 0 requests for sfbufs delayed 0 requests for I/O initiated by sendfile I just noticed that the total "mbufs in use" didn't seem to have increase when I did the 100x scaling of kern.ipc.nmbclusters (and kern.ipc.nmbufs auto-adjusted). Neither did "bytes allocated to network". Is that expected? Lars
