Redis redisson-netty thread lock

Hi,

We have setup Redis cluster and populated key/values. Some Keys contain more than 2M fields. When we call getAll of RMap using redission client, it takes more than 30 mins and goes to idle state. We analyzed the thread dump and noticed the below errors. We are using redission client (3.13.1). Is this known issue with Redisson client?

Error
