I was in an impression that if i change the assigned sql memory it shouldn't impact any online operation. However i was surprised to see this message 'SQL Server has encountered 1 occurrence(s) of cachestore flush for the 'SQL Plans' cachestore (part of plan cache) due to some database maintenance or reconfigure operations.
' right after i changed the memory. Did it flush all the plans after i changed the memory? This is on SQL 2005 64 bit standard edition.
