+ Memcache notes

6GB of memcache seems a little low for a decent sized installation,  
especially if using memcache as the caching driver.  Even if you have  
32-bit machines, you can still get 3GB+ per machine easily.  Or,  
better yet, take the splurge and buy a couple of cheap 64-bit boxes  
instead.  The great thing about memcache is that it doesn't need  
powerful, server-grade hardware to run.  In fact, that is overkill.   
Any cheap 64-bit box is going to be plenty powerful enough to handle  
the memcache load.  Quite honestly, your bottleneck will come from the  
network traffic to/from the memcache server/PHP server, and most  
likely the network infrastructure will be the limiting factor, not the  
network I/O speed on any given interface card.

Also, absolutely no reason to reboot memcache every night.  In fact, I  
highly recommend you don't, especially if you are caching with  
memcache also.  Rebooting simply loses all those hardearned  
mailbox/message caches that your servers labored to build every day.
