Are you trying to claim your EOS, but keep getting the following EOSCrowdsale error instead:
Warning! Error encountered during contract execution [Out of gas]
This usually means that the amount of gas specified in MetaMask is too low to run the instructions required by the EOS claimAll() function in the smart contract. Not only will the transaction fail, but you could also find yourself burning through a significant amount of ether in the process.
Fortunately, the fix is rather trivial. Simply set your gas limit to 5000000, and reduce the gas price to only 2 Gwei. This gas price will take a few minutes longer, but will save you a lot of ether in Tx fees.
Please let me know in the comments below if this works for you or if you face any issues. Good luck!
