Why does Aptana Studio and also Eclipse break internet after saving or downloading?

Question

Eclipse

I worked at Aptana Studio for a long time, then lately it has been annoying, the Internet connection is constantly breaking. After downloading files or one time after saving, the Internet was interrupted and the download / save failed.
I thought it was on the Internet, but for now I used others, for example, a browser, and so on, it works quietly, and after saving / loading in Aptana, it breaks the Internet. Impossible to work. Downloaded Eclipse - same thing. Because Both platforms are the same. What is the problem? Via FileZilla - works great, but I'm not comfortable working. I change files directly from the site. No local site. Can you advise how to solve the problem? or another program? Didn't find anything :(
