Ganache become disconnected after some hours

Question

I am running my program to deploy thousand of contracts and millions of transaction to interact with them, which definitely need a lot of hours. But, when i let my program running during night (without using my laptop at all), then Ganache GUI become disconnected after some hours, which cause my program to stop. and my program shows this error Error: Invalid JSON RPC response: ""

It should be noted that i turned off all option of auto sleep and choose Never/Do nothing options. Why Ganache become unresponsive after some hours ? Is there any way to keep Ganache running all the time ?

UDDATE: my code is here

const Web3 = require('web3');
const provider = new Web3.providers.HttpProvider("HTTP://127.0.0.1:8545");
const web3 = new Web3(provider);
const account1 = "0x2cAe18ac37d85CccdE2e...." // Ganache GUI
const privateKey1 ="0x19c30ab1a928ab11f18..........." // Ganache GUI

      gas: 5000000,
  };
  const signed = await web3.eth.accounts.signTransaction(options, privateKey1);
  const receipt = await web3.eth.sendSignedTransaction(signed.rawTransaction);
  console.log("Contract: is deployed at  " +receipt.contractAddress);
  var address = receipt.contractAddress;
  return address;
  // contractAddressess.push(receipt.contractAddress)


}

              await web3.eth.sendTransaction(
                // web3.eth.sendTransaction(
                {from:account1,
                // nonce: myNonce,
                to:myContAddr,
                data: myFunc
                    }, function(err, receipt) {

            } catch (error) {
              console.log(" Normal Setters: ERROR !", error); 
            //   myNonce--;

async function finalGetStatus(statusArr, address) {
  var myFunc; 
  var myFuncParams; 
  var res;

    for(j=0; j<selectorObjects.length; j++) {
      // console.log("function name: ", selectorObjects[j].func);
      myFunc = selectorObjects[j].func;

      try {
        res = await myContractInstance.methods[myFunc](...[...Array(finalGettersParams[j].__length__).keys()].map(key => finalGettersParams[j][key])).call({from: account1})  // without input
        console.log("Getter output", res);
        statusArr.push(res)
      } catch (error) {
        console.log("Getter output: ERROR !", error);
        noOfErrors++;
        statusArr.push(noOfErrors)
      }

    }       

  // return statusArr;
}

async function main() {
  myData =  fs.readFileSync('./param/param0.txt', 'utf8').split('\n');

  for(r=0; r<myData.length; r++) {

    for(let i = 0; i < finalGetters[r].length; i++){
      for(let j =0; j < finalSetters[r].length; j++){
        console.log("============TestCase No. "+r+"  Getter  g"+i+"  Setter   s"+j+"=================")
      var myReceipt = await finalDeploy(r);

      }
    }
  }
}
main().then(() => {
    console.log("ALL has been DONE !")
  })

and myData is all my testcases/parameters like this [c1(constructor), g1, g2, s1, s2, s3, g3, g4, s4, g5, g6.........]... it should be noted that these values are encoded pareamters like this [0x000000, 0x123fs000, ........, 0x23abc220000]and also noted that myData contain millions of such testcase.. in finalGetters = [g1, g2, g3,.. ], finalSetter =[s1, s2, s3...]

Try to wrap each one of your getter function calls with this:

async function rpc(func) {
    while (true) {
        try {
            return await func;
        }
        catch (error) {
            console.log(error.message);
            if (!error.message.startsWith("Invalid JSON RPC response"))
                throw error;
        }
    }
}

For example, change this:

res = await myContractInstance.methods[myFunc](xxx).call(yyy);

To this:

res = await rpc(myContractInstance.methods[myFunc](xxx).call(yyy));
