Not getting category of app after polling so many entries

[GoogleCodeExporter]

Hi,
I have got categories of app with my google account,
I had around 160000 apps. To get categories of these app,I use android market 
api; but after some days or after polling some entries, I am not able to use 
same google account,

Why is it so?
Is it because of polling so many entries?
If yes is there any other option for it? Do I need to change any settings of my 
google account?
Plesae help me with this.
