I find out from log4j log that there are 100x of this exception every day

I am using CentOS 7.3 aerospike-tools-3.12.0-1.el7.x86_64 aerospike-amc-community-4.0.12-1.x86_64 aerospike-server-community-3.12.0-1.el7.x86_64 aerospike-client-3.3.2-jar-with-dependencies.jar resin-4.0.49-1.x86_64 jdk1.8.0_121-1.8.0_121-fcs.x86_64

        }
}

I need to find out if my configuration is incorrect, the SSD is not good enough or something else?


#2

What timeout value are you giving when doing this? Do your histograms show any latency when you experience this issue?

I am using the default value of aerospike java client.

The following is the histogram
