The Application Control inventory is blank after the ePO client task SC: Pull Inventory completes successfully.

The orion.log records entries similar to the following when the MACC extension 6.1.3 and later is installed. These entries are also recorded in the server task log.
 

2013-07-22 15:04:38,050 WARN  [mfs:pool-2-thread-4] dao.DataChannelDAOImpl  - deleted 1059 rows from scor_data_channel with data_type = SCORInventory and maxchunks = 1024

NOTE: If you are using the MAC 6.1.2 extension, you must change the log level to Debug to see these errors. See KB52369 for details about changing the log level. Then, add the following entry in log-config.xml:
 

               </logger>                     

A clean-up thread runs every two hours. It deletes inventory chunks larger than the configured permissible limit entry (by default, 1024). You will see the following log entry in orion.log two to three hours after inventory is pulled:

 

Performing delete for data type : SCORInventory

## Performing delete on n* autoIds 

And:

Completed cleanup of large transactions from data channel for SCORInventory Data Type(s)

## This is the log that appears in conjunction with the above and below log messages when issue occurs.  n* can be any number greater than 1024
