As far as I can tell I've cleared the ESM log.  Both with dset, and via 
whatever log clearing options were available in the BIOS and DRAC GUI. 
Neither worked.

It was DIMM_A1 that was listed.  I replaced that DIMM, the logs, and all 
other indicators seem happy in the DRAC GUI.  It's just omreport that seemed 
to still be complaining.

In the end I did a more complete power removal and 'flea power' drain.  That 
seems to have fixed it.

Thanks for your comments.
