arduino and xively

Hi
I have a problem with my project measuring air pollution with dust sensor Sharp and Arduino. I haven’t got too much experiences. Everything going perfectly, I connected dust sensor to arduino according to the instructions. I copied source code from http://www.howmuchsnow.com/arduino/airquality/dust.ino to my arduino. Changed important topic as a feed id and code from xively. Now I measure these data and uploading to the web page xively.com but after 8 cycles sometimes 10. Arduino will stop and if you want continue. You must push the reset button. I don´t know where is mistake. I thing mistake is in network because when you ban uploading data to the xively.com. Everything is ok

If you ban the uploading by commenting out code, you also reduce the amount of memory used. Perhaps there's a clue there. Without seeing YOUR code, that's strictly a guess (but one that is consistent with the behavior you are seeing).
