Can anybody explain for me what does this message mean exactly? "16064849/9164254/9384500 requests for mbufs denied (mbufs/clusters/mbuf +clusters)" And what can i do with this? Full "netstat -m" output: $ netstat -m 445/695/1140 mbufs in use (current/cache/total) 407/255/662/65536 mbuf clusters in use (current/cache/total/max) 407/237 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) 925K/683K/1609K bytes allocated to network (current/cache/total) 16064849/9164254/9384500 requests for mbufs denied (mbufs/clusters/mbuf +clusters) 0/0/0 requests for jumbo clusters denied (4k/9k/16k) 33/964/6656 sfbufs in use (current/peak/max) 0 requests for sfbufs denied 0 requests for sfbufs delayed 56067 requests for I/O initiated by sendfile 5500 calls to protocol drain routines Sorry for my bad english.
