first time user with out of memory question

[Mauro Nicolas Infantino]

Even with enough memory, and a memcached server only working for the 
session management, there's still a chance that some session data get 
lost?

I mean, maybe memcached was not designed to store sessions, but if under 
the right conditions it works ok, it could be a nice solution.

I think the problem here is not a matter of disk storage or memory 
storage. Even sharedance, wich is designed for the sole purpose of 
managing session data, suggests the usage of a tmpfs in its readme. The 
real problem would be loosing sessions even with a memcached having 
twice the memory it needs for the sessions.
