There are three sentinels in total. This anomaly occurs every time you start it. A sentinel anomaly appears randomly, but it can be used normally.

@mrniko I tested 3.12.5, try to dump the thread stacks, then I found the issue was caused by this commit 65e4d2c7

same problem. like https://github.com/redisson/redisson/issues/3283 through the test,: this not happen in 3.12.4 this will happen in 3.12.5 or higher

My current version is 3.15.0, and I use this configuration so that it doesn’t report errors:

Config config = new Config();
config.useSentinelServers()
        .addSentinelAddress("redis://192.168.55.181:26375",
                "redis://192.168.55.182:26375",
                "redis://192.168.55.183:26375")
        .setDatabase(1)
        .setPassword("*****")
        .setTimeout(30000)
        .setMasterName("mymaster");
RedissonClient redisson = Redisson.create(config);

If I don’t set this amount of timeout, it will report an error.
