The claimAll function has to check your balances for all periods that have ended, so as more periods end, it uses more gas. People have regularly had to set gas limits to 5 million at this point to get it to succeed. The solution is to call the "claim" function for the specific period you want to claim, then it'll only use gas for the period you specify. Here's how to do this:
- Find the timestamp of the block that your contribution transaction is in. (Example Oct-12-2017 01:54:36 PM +UTC at block https://etherscan.io/block/4359379).
- Convert it to a unix Epoch at https://www.epochconverter.com/ where it says "Human date to Timestamp"
- Go to the crowdsale read contract page on Etherscan. https://etherscan.io/address/0xd0a6e6c54dbc68db5db3a091b171a77407ff7ccf#readContract
- Go down to function #17, dayFor. Enter the timestamp of the block from step 2 and click query. This is the period for your contribution.
- Optional: To double check you haven't already claimed this period/you actually have funds in this period, enter the period and your address in function #1 to see if you've already claimed and function #6 to make sure you contributed to that period.
- Load MyEtherWallet like you would be calling claimAll on the EOS crowdsale contract, but instead call claim and pass in your period #. You can set gas price somewhere from 2-10 Gwei and gas limit to 500k and it should go through just fine.
