## Symptoms

- * When the VPN software blade is not enabled, output of the "`top`" command shows high CPU usage for the "`vpnd`" process.

* After `vpnd` debug is enabled, the *$FWDIR/log/vpnd.elg* log file is flooded with CPTLS messages. **Note:** The IP address in the log entry is reversed. This is the IP address associated with the Captive Portal URL.  

  ```
  [vpnd 7385 4102367120]@CP-FW2[11 Dec 19:07:17][CPTLS] getRenegParams: lookup for key : <12.0.10.10, 63763, 1.1.168.192, 443, 6> 
  [vpnd 7385 4102367120]@CP-FW2[11 Dec 19:07:17][CPTLS] getRenegParams: return_value == NULL 
  [vpnd 7385 4102367120]@CP-FW2[11 Dec 19:07:17][CPTLS] storeRenegParams: storing key : <12.0.10.10, 63763, 1.1.168.192, 443, 6> 
  [vpnd 7385 4102367120]@CP-FW2[11 Dec 19:07:17][CPTLS] storeRenegParams: added. 
  [vpnd 7385 4102367120]@CP-FW2[11 Dec 19:07:17][CPTLS] cptls_handle_msg: done. msg=HS_NEW 
  ```

* After filtering logs in SmartConsole for **"blade:Identity Awareness"** , many log entries show "*Redirect'* .

## Cause

The `vpnd` process is responsible for the SSL/TLS negotiation of MultiPortal features such as Captive Portal, UserCheck Portal, and Mobile Access Portal. The high number of Captive Portal redirections overwhelms the `vpnd `process of the Security Gateway.
