A short while ago (perhaps due to a change in traffic), every few hours, the wireless interface becomes unresponsive, and I started seeing thousands of lines like this in: ath0: ath_rx_proc: no mbuf! ath0: ath_rx_proc: no mbuf! ath0: ath_rx_proc: no mbuf! ath0: ath_rx_proc: no mbuf! ath0: ath_rx_proc: no mbuf! Has anyone seen this problem? An mbuf leak? Or perhaps fixed something like it in a later version of FreeBSD? Would upgrading the FreeBSD version fix this? It's in a really remote location, high on a tower, and tough to upgrade :( netstat -m shows: # netstat -m 104/19096/19200 mbufs in use (current/cache/total) 101/2971/3072/3072 mbuf clusters in use (current/cache/total/max) 0/3/1024 sfbufs in use (current/peak/max) 228K/10716K/10944K bytes allocated to network (current/cache/total) 0 requests for sfbufs denied 0 requests for sfbufs delayed 0 requests for I/O initiated by sendfile 0 calls to protocol drain routines The mbufs are in fact all used up. I allocate more via kern.ipc.nmbclusters, and see the same behavior. 6.0-RELEASE-p5 FreeBSD 6.0-RELEASE-p5 #6: Thu May 18 18:02:20 UTC 2006 Thanks in advance, Stef
