EndorseError: 2 UNKNOWN: too many requests for /gateway.Gateway, exceeding concurrency limit (500) in Hyperledger Caliper

Which Caliper version are you using?

0.5.0

Which Node.JS version are you using?

v16.18.0

Which operating system are you using?

Ubuntu 18.04.6

Please provide some context for your error. For example, when did the error occur? What were you trying to achieve, and how?

I tried to execute the Caliper tool for creating records with the following commands, $npm install --only=prod @hyperledger/caliper-cli

$npx caliper bind --caliper-bind-sut fabric:2.4

$npx caliper launch manager --caliper-workspace ./ --caliper-networkconfig networks/networkConfig.yaml --caliper-benchconfig benchmarks/2benchmark.yaml --caliper-flow-only-test --caliper-fabric-gateway-enabled

What was the observed incorrect behavior?

I executed Hyperledger Fabric test network and it had no errors. When I benchmarked its performance with Hyperledger Caliper tool, it was successful. Caliper works fine for reading the records from my fabric network with any number of transaction.

When the records were created it worked fine for fixed-rate controller with transaction numbers 100,300,500, 800 but when the transactions count is increased to 1000 or above it throws the error.

To rectify the error I changed the value of gatewayService to 2500 from its default value 500 in the core.yaml file but still the error not rectified.

Please provide the error logs and their surroundings.
