Description
A user has failed to log into the teach pendant menuing system because not enough RAM memory is available to make the connection. The system might still be usable because the connection requires a predefined amount of available memory to start up.
Remedy
Add RAM memory to your system. You can also lower the memory limit required for login by changing the system variable $UI_CONFIG.$MEM_LIMIT to a lower value.
