Help debugging director problems after a period of time

["Randy Paries" <randy.paries@xxxxxxxxxxx>]

I am setting up a LVS-DR with ldirectord

I am running into a problem and I really do not know where to start
debugging.

The box is pretty well only running LVS-DR and ldirectord

Here is the problem. 
It works fine for a period of time. Then after a while(hours not minutes)
everything slows down.
The symptom is I can not longer ping my name server.

If I reboot it works fine again for a while. I tried killing ldirectord to
see if he was the problem but nope. I can ssh into the box just fine, it is
just the name resolution. I can not even ping the name server ip.(every
other box can, and if I reboot I can immediately.)

Ipvsadm takes about 30 seconds to display(must use the name server I assume)

So here is my config(for what it is worth) I am running the 2.4.20-30.9.um.1
kernel

Thanks for anyhelp or any suggestions on how to debug it
