[horde] Memcache server questions

[Kevin Konowalec]

That's exactly how it works.  That's why we have a large number of  
servers so that if one does croak it only affects a small number of  
users.  I'm not sure if there's a way to get around this.

Now there's a problem we are seeing with it.  Even with all the  
servers we still have people mysteriously getting kicked off all the  
time.  I'm not sure if this is a horde bug or if we (still) don't  
have sufficient "high tide" memcached capacity.  Since I have yet to  
find any sort of metric we can use to determine how much we'd need  
for any given load level to prevent overwrites we've just been  
playing it by ear and adjusting as necessary.
