So I am running Lubuntu and trying to get a fresh install of bitcoin-qt wallet to download the blockchain. It seems it will download the blockchain for about 30 minutes usually and then just stop. To make it continue I have to close the wallet and restart it and same thing will happen again a little later, its really frustrating. Anyone have any suggestions as to whats causing this?

Thanks.

Current Features of script are

- Spend Virtual balance to other users on the site by username
- Integrated Forum for user chat and discussion / support
- Support Ticket System
- Dashboard displaying things like balance, total sent transactions, total received transactions, user referred by upline(Referrals will get a small % of transaction fee per purchase for bringing in new users) .
- Manual withdraw system
- Transactions Page to view old transactions
- Merchant Product creation page, define product name, price, description
- IPN, allow merchants to host a pay now button per each product they want to sell, then our site will process the purchase of it.
- API, allow merchants to remotely view their balance, pay users from their selling portal.

V2 features considered-
-Make a USD to BTC conversion price total based on live market at the time of purchase.
-Make API to pay users remortly based on USD to bitcoin value so you can pay the current fiat value of Bitcoin if desired.

If you have any interest on working on this with me let me know, I may be able to offer a cash incentive. Otherwise we can just chat it up on skype or something if your just simply interested in discussing it with me.

EDIT- Forgot to say, this is developed in PHP/MYSQL

Thanks,
Jeremy.
