SMS_MP_CONTROL_MANAGER 5414 errors

[Mattatwork]

I have recently set up SMS in our organisation. We he one primary site and 3 secondary sites. The problem lies with the last secondary site that I have created. All of a sudden I am seeing lots of SMS_MP_CONTROL_MANAGER 5414 errors:

MP could not complete a task when processing Hinv.
Check the logs for clues. Possible cause: Out of disk space.
Solution: Increase the disk space, remove unprocessable files.

And the same amount of 5415 errors:

MP cannot load the hardware inventory class mapping table when processing Hardware inventory.

Possible cause: MP cannot communicate with the SQL data base.
Solution: Check the network connection between MP and the machine hosting the SQL data base (likely the PSS).

Possible cause: The SQL data base not initialized properly or corrupted.
Solution: Check the data for consistency. Recreate the hardware definition tables if necessary.

I have checked the mpcontrol.log file and this confirms that the http verifaction is okay:

Http verification .sms_aut succeeded with status code 200, OK $$<SMS_MP_CONTROL_MANAGER><Tue Jan 11 13:01:06.517 2005 GMT Standard Time><thread=2840 (0xB18)>

I have checked the web and redone the SPN's but I am still getting the error.
