From past few days, I am facing this issue on live.
I am maintaining a key in REDIS and each time system setting key in redis, It also set expire in it.
But few days back, User start saying that system behaving different. After some search, I found redis key expire set to -1. But this is not coming on test server.
I am insert this same key from website and from game. Can anyone tell me, What is going on(I think concurrency issue)?
