News: OmsVme58 crashes (P64, P65), new HasyUtils version, cups issue

• OmsVme58 crashes (P64, P65): a workaround for long running python scripts:

  In [4]: HasyUtils.assertServerRunning?
  Type:        function
  String form: <function assertServerRunning at 0x7fe62f8d72a8>
  File:        /usr/lib/python2.7/dist-packages/HasyUtils/TgUtils.py
  Definition:  HasyUtils.assertServerRunning(serverName, dbHost)
  Docstring:
  use case: 
    to ensure that long measurements consisting of series of individualScans
    are not interrupted a Tango server crashes. 
  
  what the function does:
    - get a device belonging to serverName
    - create a device proxy and evaluate the state
      + if OK, return True 
      + otherwise
        o wait until the server is no longer in the list of running servers
        o wait until the server appears in the list of stopped servers
        o start the server
  
  implementation principle: 
  
    while True:
       try:
            individualScan()
       except:
            HasyUtils.assertServerRunning( "ServerInvolved/Instance", "haspp99:10000")
  
  Another example can be found in the Spock manual, section Helpers.
  

• new HasyUtils version: contains assertServerRunning() and a fix for the bug reported by P06 (reverse piezo dscans).

• new cups package: P11 reported that the OmsVme58 server did not start:

      omniORB: Failed to bind to address :: ephemeral port.
      omniORB: Error: Unable to create an endpoint of this description: giop:tcp::
      INITIALIZE CORBA system exception: INITIALIZE_TransportError
      Received a CORBA_Exception
      Exiting
      terminate called after throwing an instance of 'omni_thread_invalid'
      Aborted
  

  Reason: it-cups (printing) used-up tcp/ip ports.

  Solution: remove cups, if no local printers are connected. Issue is under investigation.
