On a 6-stable machine with sufficient RAM, i.e. no swapping and 215MB free in 'top', I'm seeing .. imb@sarah:/home/imb# netstat -m 386/529/915 mbufs in use (current/cache/total) 384/254/638/17088 mbuf clusters in use (current/cache/total/max) 384/128 mbuf+clusters out of packet secondary zone in use (current/cache) 0/0/0/0 4k (page size) jumbo clusters in use (current/cache/total/max) 0/0/0/0 9k jumbo clusters in use (current/cache/total/max) 0/0/0/0 16k jumbo clusters in use (current/cache/total/max) 864K/640K/1504K bytes allocated to network (current/cache/total) 1405/14/0 requests for mbufs denied (mbufs/clusters/mbuf+clusters) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 0/0/0 requests for jumbo clusters denied (4k/9k/16k) 0/6/4528 sfbufs in use (current/peak/max) 0 requests for sfbufs denied 0 requests for sfbufs delayed 0 requests for I/O initiated by sendfile 28 calls to protocol drain routines What prompts this behaviour? Do I want/need to "play with" any sysctls to preallocate more space? -- Michael Butler, CISSP Security Architect Protected Networks http://www.protected-networks.net
