I did following steps to fix this problem,

• Navigate to Check Services Enabled in this Farm (Central Administration > Application Management > Check Services Enabled in this Farm)


• There was the error message
  Service: Office SharePoint Server Search
  Issue: The query server index file location on SERVERNAME is not shared. This location must be shared to allow for this server to receive propagation.
  Impact: Index propagation to SERVERNAME will fail.
  Action: Use the Office SharePoint Server Search Settings page to create the share.
  


• I navigate to the page Office SharePoint Server Search Service Settings page(Central Administration > Operations > Services on Server > Office SharePoint Server Search Service Settings)


• Set up the page.
  
  The above errors were cleared from my event log for good.
  
  I am a very happy man!!!!!!
