Logging negative buys and positive sells

API Seeking Help

I was running my algo and it was working fine, when it hit the market correction in early Aug this year.

I was using this code for generating logs:

                    buy_order_id = order_target(stock,numshares)  
                    buy_order = get_order(buy_order_id)  
                    buyprice = data[stock].price  
                    if buy_order:  
                        print "Bought %s shares of %s for %s." % ((buy_order.amount), (stock.symbol), buyprice)

The logs were working great until there were too many generated for Aug 24th:

2015-08-24PRINTSold -2081 shares of CERN for 57.57.
2015-08-24PRINTSold -3607 shares of FOX for 24.08.

2015-08-24PRINTBought -2154 shares of FB for 80.321.
2015-08-24PRINTBought -1555 shares of AMP for 111.245.

After the logging limit was exceeded once, the logs were permanently messed up for the remainder of the backtest. Is this a problem with my code, or some glitch or quirk in the IDE platform?
