decaptcher.com - mass captcha breaking problems

Hi,

I am a happy user of decaptcher.com and wrote my own small api in Java.

If I am submitting image per image, all is really perfect, but when I mass-submit, I get often(certainly) -5 server overloaded back. So how can I measure, if the server is free for more submissions? Did I oversee something in the api?

I also think, although I get back -5, the server is encoding the image and my balance goes down, do you also have that problem?

Currently, I just post the image and get immediately for the result (often -5 ), but is there any other approach to it?

Thanks,

Nobody any idea? Just to emphasize: decaptcher is really great and maybe it is my own dumbness why I have those problems.

I am still not sure about that: do they encode the image although the server is responding -5 ? If this would not be the case, there would not be any problem at all, but what I see shows different.

Are there any other 'power' users of decaptcher who could help me?

Thanks,
cooooookies
