Game boot to some operations every second
The first problem with this code is that there is too little explanation for anything. There is no documentation. There is a referenced class RedisClient for which there is no explanation of what it is and how it is being used. The variable names tend to be undescriptive. When asking other people to read code, then it is the author's responsibility to make it so that they actually can read and follow the code.

The next major problem is a classic issue for newer programmers (and something I have been guilty of myself) - big monolithic procedures, specifically checkQueue. When the size of a procedure exceeds a reasonable size (definition of reasonable vary from person to person, but certainly no more than 10 lines), then the developer should look very hard for ways to refactor it and extract out pieces of discrete functionality. In this code, everything inside the for (range &lt;- ss) block should almost certainly be extracted into a function of its own (with a descriptive function name).

I would recommend fixing these two issues and then post a new question asking for a new review of the modified code.
