This command >(or even 'sysctl net.inet.accf') runs endlessly ;-( OK; I got today's -CURRENT built and running: FreeBSD m147.whistle.com 5.0-CURRENT FreeBSD 5.0-CURRENT #60: Thu Jul 5 09:27:49 PDT 2001 root@m147.whistle.com:/common/C/obj/usr/src/sys/LAPTOP_30W i386 but it exhibits the same "hanging". And sure enough, "sysctl -a" hangs; here's that last part of its output before it does: net.inet.tcp.local_slowstart_flightsize: 65535 net.inet.tcp.newreno: 1 net.inet.tcp.tcbhashsize: 512 net.inet.tcp.do_tcpdrain: 1 net.inet.tcp.pcbcount: 27 net.inet.tcp.icmp_may_rst: 1 net.inet.tcp.msl: 30000 net.inet.tcp.always_keepalive: 1 net.inet.udp.checksum: 1 net.inet.udp.maxdgram: 9216 net.inet.udp.recvspace: 42080 net.inet.udp.log_in_vain: 0 net.inet.udp.blackhole: 0 net.inet.accf.unloadable: 0 ^C A -CURRENT kernel as recent as 2 days ago does not exhibit this, and the problem showed up yesterday. (My previous message has details such as message & dmesg logs and CVSup history.) I'll be hunting for likely commits, though I wouldn't object if someone else beats me to it.... :-) Cheers, david -- David H.
