## Symptoms

- * All clients disconnected from server
* Server_messages.log: WARN main - Unable to load server list from persistent storage. This is an expected occurrence, only for the server's initial run. (ServerListDatabaseLoaderUSM) com.checkpoint.uepm.api.epsbackend.is.EpsBackendException: Failed to read UPDATE_DIRECTORY_INFO configuration at com.checkpoint.uepm.blm.serverlist.policygeneration.ServerListIbatisRetriever.replaceOperationsList(ServerListIbatisRetriever.java:234) \~\[serverList_blm.jar:?\] Caused by: java.lang.NullPointerException

## Cause

Default (client) scanner was deleted from the database which triggers the issue with server-list initialization.  

`ServerListIbatisRetriever.java` is a class that collects all the information and configurations from the database and updates server-list with it. One of the default and important configuration is CLIENT SCAN data in the database.
