I have the same problem with netgraph on 7.1-RELEASE, mpd 5.2, AMD Phenom. Dummynet, divert and pf are disabled in the kernel. While swi1:net (aka netgraph) is using 100% of CPU time m_tag_locate() and ng_iface_output() are constantly called from the infinite loop. Sergey, could you provide the content of mpd.conf and the output of "ngctl types". -----Original Message----- From: owner-freebsd-net@freebsd.org [mailto:owner-freebsd-net@freebsd.org] On Behalf Of Sergey Pronin Sent: Thursday, February 12, 2009 9:07 PM To: freebsd-net@freebsd.org Subject: Synopsis: process swi1:net gives 100% CPU usage. Synopsis: process swi1:net gives 100% CPU usage. Not depending on the conditions (no heavy load, not a lot of traffic passing through, not a lot of ng nodes) server stops to work properly. 1) swi1:net gives me 100% CPU usage. 2) server is not responding to icmp echo requests 3) ssh of course not working 4) mpd has an "ngsock" state at the top 5) tasq of the em0 card using 0% of the cpu. 6) rebooting the server helps.
