Sorry, but I have to disagree... We've discussing this issue at linuximq list and it is not obvious that the postrouting hook is the culprit for all the reported problems. I've being using postrouting for long with no side effects, no crashs, no oops. More investigation on it is needed.
What is a known issue is that one should not try to touch localy generated traffic with IMQ. This is known to cause problems, so you better not try it.

IMQ is quite stable when used on ingress only just dont touch postrouting and it will be ok
you can use either old version, either my new one
which does not need to patch kernel and iptables
you can find it at http://pupa.da.ru/imq/
(but it may be incompatible with some conntrack modules)

Subject: Re: Questions about IMQ's stability
Hi Jason, right now I don't think anybody can assure stability on IMQ. My experience is that IMQ works fine in my enviroment that is a 2.4.23 PPPoE concentrator with ~70 users... It is up and running for more then a month without any problems.
What I would suggest you is to make some stability tests in a lab before putting it into production...
What kernel version will you use? It seens that 2.4.23 is the best bet for now.
IMQ has being unmaintained but there is a groups of people trying to get it on its way again. You can reach the brand new group at: http://www.linuximq.net ... There is
not much new things yet, the work is just starting, but you, and everybody else, is more then welcome to join us there and share your results and needs.
tks and good luck

Hi,
There have been a number of threads lately discussing IMQ's
stability
(or lack thereof). I am about to roll out a new router and I
quite
badly need IMQ's functionality. This is a production
environment,
though, and random panics of course aren't acceptable.
My question is are there any circumstances under which IMQ is
_stable_?
The router will have about 6 interfaces, 2 of which will be
to
(separate) upstream ISPs. The router must be able to manage
the
bandwidth fairly between the remaining four interfaces, so I'll
need
IMQ. Perhaps there is another solution?
Thanks, Jason.
