If this error occurs "Error occurred during CO3/DO3 processing: Error when attempting to call Fulfillment Lookup in Libra dos: SERVICE FAULT : String : Connection reset" then what might be the reason

  1. Serial/IMEI number might be invalid

  2. ALSB might be hung

  3. CO3 might be sent to some other test bed

  4. None of the above

B Correct answer
Explanation

The error indicates a service‑level failure during a lookup, which typically occurs when the ALSB (Application Layer Service Bus) is hung and cannot complete the request. An invalid serial/IMEI would cause a validation error, and sending CO3 to another test bed would not produce a connection‑reset fault, so those options are wrong.
