There are a few problems that have been fixed (or worked
around) after the release of 7.0. For example, look at
PR kern/113548 which has a work-around in 7.1. Your
problem description sounds like it could be caused by
the same problem.
Therefore I recommend you update to 7.1 or 7-stable.
Best regards
Oliver
Hello.
System updated to:
[r...@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 r...@***:/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 :(

Please do the following (when dummynet will hang next time):
1) Grab the output of follwing commands:
sysctl net.inet.ip.dummynet
ipfw pipe show
2) wait a bit (30 seconds should be enough)
3) do 1) once again.
Examining counters may help in understanding problem.
