Inconsistent behaviour

[randunel]

I have a haredis setup with multiple clients (5 clients per instance) and multiple node.js instances (about 10 instances default, 25+ instances on server load).
It seems like client.set sometimes fails to set the key, since client.get often returns null for the same key. I no longer have expire time.

Have such problems been reported before? haredis clients are getting connected and disconnected as node instances go up and down, could this be the source of the problem?
