Recently, I encountered a Application Metering problem, which was evidenced by constantly seeing the following three errors in the Altiris log files.

The top error, outlining the fact that licensing had failed was frustrating, and after reviewing the licensing page and seeing that all was in order, the issue became more challenging.  I did some further review and analysis of the log files.  I noticed this statement:

Cannot insert the value NULL into column '_ResourceGuid', table 'custom_table_name'; column does not allow nulls. INSERT fails. (custom table name was actually populated with a name from a specific database)

It became clear that as a part of collecting the application metering data, a custom table was also being populated. Further, that the custom table definition did not permit NULL values to be included in the _resourceguid column of that table, and that NULL values were coming in from the managed client machines.

Once the custom table definition was changed  to support NULL values for the _resourceguid column, the problem and errors disappeared.  And licensing had nothing to do with it.
