[horde] still having problems with dropped sessions

Okay I've added 4 machines with 1.5 Gigs each dedicated to  
memcached.  I just added them to the list so the original memcached  
boxes are still in the loop... so I have a total of 7Gb dedicated to  
it which I'm sure is complete overkill but if it works I'll be  
pulling the original ones out and leaving 6Gb in.

BUT not long after I added the other machines in I was getting  
complaints about people being booted again.  I'm thinking that's  
likely due to them having logged in before I made the changes and  
thus they didn't get the conf file changes and so are locked to the  
original 2 machines for the remainder of their session.  Does that  
sound reasonable?  Or could there be something else?
