IBM Director Common Agent - SNMP Hardware Status Polling Failing

I have a customer that is running a data center full of IBM servers.  They have installed the IBM Director Common Agent on their servers (6.3.3) as per the Troubleshooting Hardware Monitoring guide.  While the hardware monitoring always starts off fine, it seems to fail after a few hours.  All of the servers are X Series servers (X3550, if I remember correctly).

Has anyone else experienced a similar issue when trying to poll the hardware status from the IBM Common Agent?  Reporting from the Common Agent to the IBM Director Console works without issue and polling from the standard performance MIB does not stop, only polling from OIDs that are covered in the IBM-SYSTEM-ASSETID-MIB.

In order to return the server to proper monitoring of the IBM hardware (albeit only for a few hours) the client needs to restart the SNMP service on the server (restarting the Common Agent has no impact) and run a List Resources on the node.  I am working to verify the List Resources part as that one confuses me -- so there is a little more testing to come there.

I found a few links in IBM's forums that suggest similar issues, but they are all dated -- and with no resolutions posted!
