Problem conclusion

• TPC Server waits forever a ping response which could be blocked
  by firewalls.
  
  The fix is to put a timeout limit to how long the server waits
  for a ping response.
  
  If the Agent computer does not respond to ping in the timeout
  interval then the Agent will be marked UNREACHABLE.
  
  APAR is targeted for the following maintenance packages:
