This event can be recorded for various problems. At the bottom of the event description, there might be the actual useful information. In troubleshooting this, the administrator should only apply suggestions for the type of error experienced, not for all event id 373. Example:
SQL Server does not exist or access denied. - Command: getListBESdatabases - Indicates that the Blackberry service was unable to contact the SQL server or the account used to access it does not have sufficient rights. The event also records the command that was attempted.
Query timeout expired - Command: getListBESdatabases - Indicates that while the Blackberry service was able to contact the SQL server, the command took too long to return the expected answer. It appears that the SQL server is experiencing problems.
