fastcgi_read_timeout with PHP backend

[B.R.]

Hello Maxim,

I spent a lot of time trying to figure out what is happening.
It seems that after some service restart, the problem sometimes disappear
before coming back again on the following try.

I finally managed to capture the debug log you'll find as attachment. I'll
need your expertise on it, but it seems that the tcpdump show stuff which
do not appear in the nginx output.
T
​he archive attached is as much self-contained as possible, including :
- Server information (uname -a)
- Nginx information (nginx -V)​: self-compiled from sources since I needed
to activate --with-debug
- tcpdump between php and nginx (+ 'control' file containing the standard
output of the tcpdump command, including interface and packet numbers
information only)
- nginx error_log (set on 'debug)
- browser output (copied-pasted from source, you'll see there is no end
tag, thus proving the output is brutally cut out)

If I might be of any help providing some other information, please let me
know
