Sorry I sent that last reply directly to you. I wish this mailing list set the reply address as the
mailing list address. 

Also I've noticed that after you remove the problematic PC or network connection, it takes a few
minutes for the m0n0wall to clear itself up and return back to normal. I assume this may be from
having to process through the existing memory buffer, but that is speculation. 

Although we've had some crazy ideas and theories about what has caused these errors on various
sites, it has always come down to one PC on the network causing problems. Antivirus going haywire,
some spyware sending out SPAM, we had a system yesterday that the APC UPS software was going nuts
and causing it to grind the network card to a halt.

128MB should be fine. You can try throwing together a generic-pc box with a bunch of memory and a
faster processor to see if it is a hardware problem, it only takes a few moments.

How much memory is in the system running m0n0wall?

I have seen this in a few cases, and in every case it has been some sort of DoS attack, usually from
inside the network. It is very unusual to exhaust memory buffers under normal conditions.
Essentially the m0n0wall is trying to store traffic locally before forwarding it to its destination,
but it is having too much traffic sent to it and it does not have memory to store it all before
sending it off.

Check network activity, start unplugging ports on the switch if you need to, it can be a pain to
chase these down. While it could be something entirely different, like I said all my cases have
involved some infected PC on the network sending out SPAM mail or other bad traffic at very high

For what its worth, traffic shaper has always been uselessl to me in these situations.

last night my wrap broke down and when i plug in the cable i read this out :

all mbuf clusters exhausted, please see tuning (7).
all mbufs exhausted, please see tuning (7).
tried to reinstall with diffrent versions, but without any luck
read about this problem on some bsd sites. but is it the hardware that broken ???
the wrap runs for 1 min the its breaks down..
best wishes
