ganache-cli 6.7.0 - Could not connect to your Ethereum client with the following parameters

Hi Team,

Our travis tests are running on ganache-cli version 6.7.0. ganache-cli is behaving strangely. Issue we are facing is that ganache is getting killed abruptly. After restarting the build multiple times, test passes. Below is the build url: https://travis-ci.org/mosaicdao/mosaic-1/builds/620642401

{ Error: 
Could not connect to your Ethereum client with the following parameters:
    - host       > localhost
    - port       > 8545
    - network_id > 1575468748758
Please check that your Ethereum client:
    - is running
    - is accepting RPC connections (i.e., "--rpc" option is used in geth)
    - is accessible over the network
    - is properly configured in your Truffle configuration file (truffle-config.js)

Below is the truffle config:

module.exports = {
  networks: {
    development: {
      host: 'localhost',
      network_id: '*',
      port: 8545,
      gas: 12000000,
      gasPrice: 0x01,
    },
  },
  compilers: {
    solc: {
      version: '0.5.8',
      settings: {
        optimizer: {
          enabled: true,
          runs: 200,
        },
      },
    },
  },
  mocha: {
    enableTimeouts: false
  },
};

Ganache is being started with below command:

./node_modules/.bin/ganache-cli" \
    --accounts=1000 \
    --defaultBalanceEther=10000 \
    --gasLimit 0xfffffffffff

Below is how we are creating our web3 object:

const web3 = new Web3('http://localhost:8545');

How can above issue be fixed?

I also get this error when I perform multiple tests by truffle test.

Truffle v5.1.51 (core: 5.1.51)
Solidity - 0.4.24 (solc-js)
Node v12.16.1
Web3.js v1.2.9

Ganache CLI v6.12.1 (ganache-core: 2.13.1)

@cgewecke test passes with below package versions:

"ganache-cli": "6.8.1-beta.0",
"truffle": "5.0.43",
"web3": "1.2.1",

Can you please explain the issue in more details?
