We're running a Redis 2.8.4 instance on a Ubuntu 14.04 server where we're experiencing problems with a key that's being reset to 0.
It's a key we're only running INCR commands on, but every few months it goes to 0. Last time it was at around 29000, so it's not a very big number.
In our codebase, there's only 1 place where the key name is referenced, so I'm a little confused about what's happening.
The only thing i have to go on is an entry in the log (it's a standalone server, no slaves):
