I have a local redis server (version: 6.2.6), redisson(3.16.0) and after a few mins of application startup, I see errors related to Redis connect timeout in logs: Unable to send PING command over channel: [id: 0x87172b36, L:/127.0.0.1:65454 - R:localhost/127.0.0.1:7000] [java] org.redisson.client.RedisTimeoutException: Command execution timeout for command: (PING), params: [], Redis client: [addr=redis://localhost:7000] [java] at org.redisson.client.RedisConnection.lambda$async$1(RedisConnection.java:219) ~[Redisson-3.16.0.jar:?] [java] at io.netty.util.HashedWheelTimer$HashedWheelTimeout.expire(HashedWheelTimer.java:672) ~[netty-all-4.1.jar:4.1.48.Final] [java] at io.netty.util.HashedWheelTimer$HashedWheelBucket.expireTimeouts(HashedWheelTimer.java:747) ~[netty-all-4.1.jar:4.1.48.Final] [java] at io.netty.util.HashedWheelTimer$Worker.run(HashedWheelTimer.java:472) ~[netty-all-4.1.jar:4.1.48.Final] [java] at io.netty.util.concurrent.FastThreadLocalRunnable.run(FastThreadLocalRunnable.java:30) ~[netty-all-4.1.jar:4.1.48.Final] [java] at java.lang.Thread.run(Thread.java:829) [?:?]

And sometimes during application startup, I see this error (not reproducible):

Caused by: RedisConnectionException: Unable to init enough connections amount! Only 2 of 10 were initialized.

Redisson SingleServer Config: .setConnectionPoolSize(15) .setConnectionMinimumIdleSize(10) .setConnectTimeout(3000) .setRetryAttempts(0) .setTimeout(60) .setIdleConnectionTimeout(5000) .setPingConnectionInterval(3000)

Is this related to pingConnectionInterval settings? Also one other question, is retryAttempts = 1 considered as first attempt?

Check your network connection.

Is this related to pingConnectionInterval settings?

Yes.

Also one other question, is retryAttempts = 1 considered as first attempt?

Considered as a single attempt.

set idleConnectionTimeout=pingConnectionInterval

the problem does not reappear。 @mevemula You can try, a temporary solution。
