I got this error, I've had it for a couple weeks, and it doesnt seem to effect anything on my site, but I'd like to fix it anyway.

This is the error:
ad_cache_memcache.module: Unable to syncronize cache: Memcache is not installed, memcache_add_server not found.

Only guessing from your error message, but it looks like the Advertisement module (http://drupal.org/project/ad) is configured to use Memcache (an optional PHP performance enhancer), but you don't have it installed (http://drupal.org/project/memcache).

Also, there are updates available for one or more of your modules or themes. :)
