:Just to provide a little bit more info, Alex, one of the developers of :icecast said that a person running OpenBSD had kernel panics under similar :conditions but that it was never resolved. : :The machine is remote, but I can have someone stand by and record the :kernel panic message while I crash it, if you it'd be useful (probably). : :--- :Jesse <j@lumiere.net> :http://www.lumiere.net/ On the face of it it sounds to me like icecast is perhaps making the socket buffers bigger --- maybe too big. The default socket buffer size is 16K receiving, 16K sending. 40 x 16K x 2 = 1MB. If icecast is increasing the size of the socket buffers, this value can explode. netstat -tn on a running system ought to give you some idea about that by seeing how backed-up the socket buffers get. -Matt Matthew Dillon <dillon@backplane.com> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
