Critical Error! in run-time-reconfigation of master agent

  Hey,
   
  I'm using net-snmp-5.3.0.1, on Linux.
   
  I'm trying to invoke the master agent's reconfigure option (either by using  'kill -s HUP pid',
  or by setting versionUpdateConfig to 1).
   
  But both ways, the master stops functioning (It functions well before i invoke the re-configuration), and returns 'no such name' for every query.
   
  I recall this feature worked for me in the past, what could have gone wrong?
   
  thanks,
  Erez.
