## Symptoms

- * Policy installation fails with error:  
  `
  Installation failed. Reason: TCP connection failure (port=18191)(IP= `*IP_address_of_Security_Gateway* `) [error no. 10]`  
  `
  Load on Module failed - no memory`   

* Fetching policy on the Security Gateway under debug ('`fw -d fetch `*IP_address_of_MGMT_Server*') shows incorrect Security Gateway's HostName:

  ```
  
  Fetching FW1 Security Policy From:
  get_policy: Explicit IP is used. This IP can take precedence in the fetch .
  get_server_info_for_fetch: an IP (Hex_IP_Address) with precedence was found
  opsec_init_entity_sic: called for the client side
  opsec_init_entity_sic: Authentication not initialized...
  opsec_init_entity_sic: in a CP product - no rules added to SIC

  opsec_auth_client_connected: connection to server failed.
  ......

  OPSEC_SET_ERRNO: err =  8  Comm is not connected/Unable to connect (pre =  0)
  ......
  Reason: TCP connectivity failure ( port = 18191 )( IP = IP_address_of_MGMT_Server )[ error no. 10 ].
   Policy Fetch Failed
  ```

* Rebooting the Security Gateway may resolve the issue for a while.

## Cause
