After using ldirector for many years without problems, we recently began
having services drop out.

I should say that I don't actually believe its ldirector per se, but
ipvs and/or the kernel.

I don't know exactly what caused the problems to start, but I suspect it
was adding a new service.

Is there a limit to number of ipvs rules I can have?  Or the number of
connections I can have open at once?  Is there some kernel param I need up?

When the service drops out, the ipvs rules are still in place according
to ipvsadm -L.  Rebooting the machines seems to fix the issue for a
little while.   When a service drops out, it will often only affect some
users and not others.

Some background:
There are two identical boxes, they are running the 2.6.30.2 kernel.
Both boxes behave the same way.  I'm using the latest ldirector (as of a
few days ago). They are running in NAT mode.
