Background JedisConnectionException: Unexpected end of stream

[eric-martin]

Jedis v3.8.0 (Spring Boot 2.7.x)
Redis v5.3.3

We are getting this error 20x a minute (10 idle connections, eviction every 30s) after upgrading Jedis:

redis.clients.jedis.exceptions.JedisConnectionException: Unexpected end of stream. at redis.clients.jedis.util.RedisInputStream.ensureFill(RedisInputStream.java:202) at redis.clients.jedis.util.RedisInputStream.readByte(RedisInputStream.java:43) at redis.clients.jedis.Protocol.process(Protocol.java:165) at redis.clients.jedis.Protocol.read(Protocol.java:230) at redis.clients.jedis.Connection.readProtocolWithCheckingBroken(Connection.java:352) at redis.clients.jedis.Connection.getStatusCodeReply(Connection.java:270) at redis.clients.jedis.BinaryJedis.ping(BinaryJedis.java:384) at redis.clients.jedis.JedisFactory.validateObject(JedisFactory.java:214) at org.apache.commons.pool2.impl.GenericObjectPool.evict(GenericObjectPool.java:745) at org.apache.commons.pool2.impl.BaseGenericObjectPool$Evictor.run(BaseGenericObjectPool.java:160) at org.apache.commons.pool2.impl.EvictionTimer$WeakRunner.run(EvictionTimer.java:113) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:515) at java.base/java.util.concurrent.FutureTask.runAndReset(FutureTask.java:305) at java.base/java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:305) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at java.base/java.lang.Thread.run(Thread.java:834)

Normal operations are working fine (read/write to the cache).

This error doesn't happen with Jedis v3.3.0 (Spring Boot 2.4) against the same Redis instance.

This error also doesn't happen with Jedis v3.3.0 against a Redis v6.0.9 instance.

Anything to try besides upgrading Redis?

Try the latest from Jedis 3.x release.

[eric-martin]

Same error with 3.9.0 and 3.10.0

[sazzad16]

What is log level in 3.10.0?

[eric-martin]

Still Error

[sazzad16]

Sorry, couldn't help.
I had few possible cases in my mind and your info matches with none.

BTW, my understanding is that this error also happens with 3.3.0. It just isn't logging those errors.
