I’m using nginx 0.6.32 on debian 4, so far without a single problem.

Could you add $path_info variable to access_log format for this location
to see whether this is nginx or PHP bug ?

Hi Igor,

Mostly this works fine but in some cases $_SERVER[‘PATH_INFO’] returns
TE_ADDR.
Any ideas?

You’re right, the variable contains the correct value in the log file!
This is going to be nasty… Will check if there’s a problem with php
5.2.5.

If you can easy reproduce the bug, could run tcpdump to insure that
nginx pass correct PATH_INFO to backend.

I can easily reproduce this error, it happens in about 30% of all
requests!
Unfortuantely I can only reproduce this on one server - a virtual server
where I don’t have access to raw packets. I guess there’s no way to use
tcpdump there but I’ll try it.

I could use a fast-cgi wrapper to check it too. Do you know a script I
could use to do that?

On BSD you may try ktrace to see all process I/O. I do not know
if strace/truss may do this.

It’s not an nginx problem!
Oh and using netcat is probably easier… The output doens’t look great
but
it’s readable.
