Exception calling "save_configuration"

While running the PSConfigArchive script it is failing here.

 

Saving Configuration to file f5lb01-2013020{7}-11580{5}.ucs

 

Exception calling "save_configuration" with "2" argument(s): "Exception caught

 

in System::urn:iControl:System/ConfigSync::save_configuration()

 

Exception: Common::OperationFailed

 

primary_error_code : 16908289 (0x01020001)

 

secondary_error_code : 0

 

error_string : Error saving configuration"

 

At C:\Scripts\newConfigArchive.ps1:94 char:56

 

+ (Get-F5.iControl).SystemConfigSync.save_configuration <<<< ($config_name, "

 

SAVE_FULL");

Any suggestions would be much appreciated.
