[Condor-users] Negotiator gets stuck

Dear all,

I hope somebody can clear up this situation for me. 
It is more than often in our environment execute nodes die fir various
reasons. But the Condor
is designed to cope with exactly this kind of environment, right?

Then why the Negotiator is failing to bypass a single node, which it cannot
communicate with?
Instead it stops submission process altogether until this node in question
is dropped completely
from the pool. I only suppose that my config settings are not quite right
somewhere. Is there 
anything I can change on the server to make Negotiator to disregard nodes it
is having difficulties to 
communicate with?
