Domino messages appear after upgrading to 8.5.1

With a customer's environment running Domino 8.5.1 FP2 I have noticed a strange message in the console stating:

UpdateStaleCacheEntries: Setting GCF_MATCH_SINGLENAME flag in cached Names list for UserName [CN=First Last/OU=orgu1/OU=orgu2/O=org/C=US], now = 05/21/2010 01:16:43 PM, timeout =

After some google searching I found an IBM article:

http://www-01.ibm.com/support/docview.wss?uid=swg1LO45992

stating that the issue will be fixed in the next release ( spr NFOL7XGJW3 )

I have yet to try running maintenance on the server's address book, but it seems to be a harmless message. The address book was also upgraded to ODS51 recently.
