@mp911de Is it possible for you to provide some inputs here?

mp911de commented 9 months ago

Without context, a wire trace or a way to reproduce, I'm not able to diagnose what's going on.

I am facing similar issue . Error message is the same as this https://github.com/redis/lettuce/issues/1796.

I am using several microservices. Each one validates requests through bearer token . Redis and Lettuce is used in User-Service , for saving and fetching renew token for a user . As , this issue is not regular, we get this once in a while, So even I don't know how to regenerate this issue. I am guessing this maybe because of high amount of requests .

Please let me know how to solve this

@mp911de We are using Redis pubsub (aws elasticate nodes with cluster mode disabled) for publishing/subscribing. now we are trying to move to the cluster mode enabled one to achieve default autoscaling provided by AWS. the cluster is going into a modifying state we are getting the above errors. currently, i'm using lettuce 6.3.0 RELEASE for this testing.
