Hello.

System updated to:
[root at taurus /usr/home/qwe]# uname -a
FreeBSD *** 7.1-RELEASE-p3 FreeBSD 7.1-RELEASE-p3 #0: Thu Mar 19 
16:31:53 EET 2009 root@***:/usr/obj/usr/src/sys/QWEKRN70 i386

but once trouble has repeated (30 mins ago).


After that I change my sysctl variables:
net.inet.ip.dummynet.io_fast=1
net.inet.ip.dummynet.debug=1
net.inet.ip.dummynet.hash_size=16384 (from 512)

What can I'll to do?

Sorry for my bad English :(
