Hello all.
I am trying to look into this error msg I am getting, almost all, from bots, 2 or 3 /hour average.
[Tue Aug 09 11:58:08 2011] [warn] (104)Connection reset by peer: mod_fcgid: read data from fastcgi server error.
[Tue Aug 09 11:58:08 2011] [error] [client 66.249.72.206] Premature end of script headers: file.php
Sometimes it displays a referrer from google.
http://www.google.com/url?sa=t&source=web&cd=1&ved=0CBkQFjAA&url=http%3A%2F%2Fwww…
I reproduce the url and it load in a half second.
I cannot realize what is the problem or at least how to make a research.
Maybe a punctual excess of concurrent queries from bots?
Anyway would reflect this behavior in 1 load time, isn’t it?
I need some clues please.
Thanks in advance.
