You can increase the max simultaneous connections parameter, 4096 is not that much. Also, install a version with maxconns_fast (for instance 1.4.10) if you want immediate failure on maxconns (you'll get a "ERROR Too many open connections"). But the best practice will be to set a timeout on your application for memcache connections.
