Did you get to confirm if the request was really going to the server or not?  If it is not, then all of the other suggestions above are completely invalid.

I observed i start getting HTTP ERROR 0 when i have around 1600 concurrent calls on machine with media. Although i see no sign of system overload either on FS (load average < 1.8) or Apache (load average < 4,75). Both have plenty of RAM and bandwidth free.
