To resolve this issue, you must create a custompackage for the VoyenceControl CiscoIOSRouterPrompts.xml file on every device server. To create a custompackage for the VoyenceControl CiscoIOSRouterPrompts.xml file, do the following:

1. Source /etc/voyence.conf as follows: . /etc/voyence.conf
   
2. Use the following command to create a custompackage directory structure for the file to be edited as follows:
   
   mkdir -p $VOYENCE_HOME/custompackage/pkgxml/CiscoIOSRouter
    
3. Use the following command to copy the file to be changed into this new directory as follows:
   
   cp $VOYENCE_HOME/package/pkgxml/CiscoIOSRouter/CiscoIOSRouterPrompts.xml $VOYENCE_HOME/custompackage/pkgxml/CiscoIOSRouter
    
4. Edit line 38 in the CiscoIOSRouterPrompts.xml file to match the following:
   
   <Expr><![CDATA[Invalid input"^%"[Dd]uplicate"Bad mask"Unable to read configuration.\s+Try again later]]></Expr>
    
5. Save and quit the CiscoIOSRouterPrompts.xml file as follows: :wq!
    
6. Restart the voyence service as follows: /etc/init.d/voyence restart
