Environment
 Novell Vibe Desktop client 2.0
  
Situation
 If the Mac's network is interrupted (put it to sleep, turn off WIFI, disconnect VPN, etc.)
 while the Vibe Desktop client is downloading files, it can hang 
forever. When this happens, the Vibe Desktop client needs to be 
restarted.
  
Resolution
 A fix for this issue is available in the Novell Vibe Desktop 2.0 (June 1, 2015), available via the Novell Downloads.
