Memory question about servicestack HOT 2 CLOSED

A question best asked on the Redis mailing list:
http://groups.google.com/group/redis-db

Although when it happened in our environment, Redis kept running its just that 
writes stopped and it started to get really slow. Although a very unhealthy 
situation to be in. If you think you will run out of memory ensure you have 
Redis VM enabled (v2.0+):

And it will sway the least frequently used values out to disk.
