Hi Terrence, Those warnings are harmless. It's more an indication that the data may drop out of cache more quickly. For large data stored in cache, we have to chop it up and store under a bunch of different keys, and it's easier for one of those to disappear.
This just sounds like your server bumped up against memory limits. Is swap enabled on the server? You may need to tune your apache settings to prevent too many processes. Also, make sure memcached is both running and being used by Review Board (check the cache info in the Administration UI). If it's for some reason using local memory caching, Apache is going to bloat up. Other tips I'd suggest is moving the database and memcached servers onto different machines, to give more breaking room to Apache. This will help with increasing performance overall.
