## Symptoms

- * SmartConsole shows these Anti-Bo logs:

  * Log Info:
    * Blade: `Anti-Bot`
    * Product Family: `Threat`
    * Type: `System Alert`
  * Forensics Details:
    * Description: `Error occur while accessing:<URL>`

* There are RAD log files in the `$FWDIR/log/rad_events/Errors/` directory on the Security Gateway.

* RAD error logs (`$FWDIR/log/rad_events/Errors/flow_<NUMBER>`) contain lines like these:

  `[rad_decrypted_response_task.cpp:134] CRadDecryptedResponseTask::decrypt: [ERROR] response size is 1030496' code limit to 1000000`


  <br />


  `[rad_decrypted_response_task.cpp:80] CRadDecryptedResponseTask::getResponseString: [ERROR] failed to decrypt response 0xdc21b440`


  <br />


  `[rad_response_task.cpp:67] CRadResponseTask::run: [ERROR] can not get response string`

## Cause

The RAD decrypt function cannot handle a payload larger than 1,000,000 bytes.

Because of that, the response from ThreatCloud cannot be decrypted, the Anti-Bot Software Blade cannot properly analyze its content and shows an error.
