## Symptoms

- * Errors in SmartView Monitor after gateway upgrade:
  * ERROR: 'Application Control' is not responding. Verify that 'Application Control' is installed on the gateway. If 'Application Control' should not be installed verify that it is not selected in the Products List of the gateway (SmartDashboard \> Security Gateway \> General Properties \> Software Blades List).
  * ERROR: 'URL Filtering' is not responding. Verify that 'URL Filtering' is installed on the gateway. If 'URL Filtering' should not be installed verify that it is not selected in the Products List of the gateway (SmartDashboard \> Security Gateway \> General Properties \> Software Blades List).

  <br />

  <br />

* Security Gateway was not rebooted after upgrade, neither were the Check Point services restarted with `cpstop;cpstart` commands.  

* The `$FWDIR/appi/update/appi_status.C` file has been replaced from a new installation and is up to date.

* The `cpstat appi -f subscription_status` or/and `cpstat urlf -f subscription_status` shows an empty values.

## Cause

Some mechanisms in SmartView Monitor will not be refreshed until a *cpstop;cpstart* or machine reboot have been performed.

This can be tested by deleting the *appi_status.C* file while the services are running and seeing that SmartView Monitor will continue to show "OK" until a reboot or *cpstop;cpstart* .  

APPI/URLF statuses are handled periodically in user mode by CPD process.  
CPD process samples *$FWDIR/appi/update/appi_status.C* file every minute and writes it to the shared memory.
