Trying to debug a 503 with PHP

[digx]

Hey guys,

I'm trying to debug a 503 error with PHP. I'm pretty sure I have the default settings for LSWS set up and I compiled PHP using LSWS. I get nothing in stderr.log

Here's what I get in the INFO log:

INFO [66.176.**.**:60756-0#my.website.com] ExtConn timed out while processing.
INFO [66.176.**.**:60756-0#my.website.com] connection to [uds://tmp/lshttpd/my.website.com_lsphp.sock] on request #0, error: Connection timed out!
NOTICE [66.176.**.**:60756-0#my.website.com] oops! 503 Service Unavailable
NOTICE [66.176.**.**:60756-0#my.website.com] Content len: 0, Request line:
GET / HTTP/1.1

Any ideas on how to debug this? Need more info?

Thanks!

You should "strace/truss/ktrace" the lsphp5 process handling the request.
try a "phpinfo" page to get the lsphp5 process fired up, then strace it with command

strace -p <pid_of_lsphp5>

Then send the request with problem.

No PHP process gets started though. Any ideas?

I tried the troubleshooting but nothing helped. Any ideas?

Have you tried to run
lsws/fcgi-bin/lsphp... -i

from command line, I think it wont run at all.
