Can't reset Solidity contract array variable

Question

I'd like to reset the players dynamic array variable in the following contract:

pragma solidity ^0.4.17;

contract Lottery {
    address[] public players;
 
    function enter() public payable {
        require(msg.value > .01 ether);
        players.push(msg.sender);
    }
    
    function pickWinner() public {
        players[0].transfer(this.balance);
        players = new address[](0); // <------- HERE
    }
    
}

Pushing new addresses in the array works just fine, but resetting it to an empty array doesn't work: I get a The transaction ran out of gas. Please increase the Gas Limit. error (even when I increase the gas limit). I've also tried delete players and players.length = 0 but nothing works.

Any suggestion?

Answer 1

Your code just works fine for a 5-element array but the longer array you get, the more gas transaction consumes.

In this case, you can increase your gas limit. There is no problem with your code.
