Hi. I have a FreeBSD 9.1/amd64 machine. It runs HAProxy and runs out of various things frequently. Sometimes it's mbufs. netstat -m: 68202/1698/69900 mbufs in use (current/cache/total) 41449/1229/42678/2622144 mbuf clusters in use (current/cache/total/max) 41449/1175 mbuf+clusters out of packet secondary zone in use (current/cache) 26405/538/26943/3276800 4k (page size) jumbo clusters in use (current/cache/total/max) 0/0/0/6400 9k jumbo clusters in use (current/cache/total/max) 0/0/0/3200 16k jumbo clusters in use (current/cache/total/max) 205568K/5034K/210603K bytes allocated to network (current/cache/total) 0/0/0 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 How can I increase "mbufs," as they appear above, and "mbuf clusters," as they appear above? Thank you. -Boris
