When managing large networks or equipment with many interfaces, you may have to increase a timeout property: the com.dorado.bom.lock_timeout property in owareapps\installprops\lib\installed.properties (originally in owdatabase.properties).
Copy that property into installed.properties, then increase this setting based on the equipment managed. Generally, you should set this value to the maximum number of interfaces you expect your network elements to have. For example, if the element is expected to have 500 logical interfaces then the timeout value should be set to 500.
The minimum recommended timeout value is 60 seconds.
