|
| Jan 21 09:50:15 s kernel: uantum of class 10056B is small. Consider
r2q change

| and so on...
|
| What is wrong with the script ? Why doesnt HTB3 like it ?
These messages appear because of too small rates or ceils for that
classes (10:056B, 10:0578, ...). The implicit value for r2q is 10 and
because of this the quantum value is too small. "Consider r2q change"
it's a good ideea indeed ;-)
You can take a look at devik's faq page, maybe it can help:
http://luxik.cdi.cz/~devik/qos/htb/htbfaq.htm
I don't know if that assertion has the same reason, I haven't noticed
something like that in my logs.
