[Condor-users] Error: Could not connect to negotiator ((null))

[Johnson koil Raj <johnson.raj@xxxxxxxxx>]

Hi

Condor is frequently giving this message. 
Error: Could not connect to negotiator ((null)). So the Job for Idle State for some time till the Negotiator is available.

#condor_status -negotiator 
       gives nothing.

That time at Negotiator Log is at 
10/15 18:41:36 ---------- Finished Negotiation Cycle ----------

After some time the  
#condor_status -negotiator 
  give the Machine Name which is Running Negotiator
condor_q -better -analyze command also works fine.

That time Negotiator Log is
