I have multiple virtual webs running Wordpress but this one started to throw errors and I am unable to find the problem.
Apache says:
[Tue Jul 30 14:13:40 2013] [error] [client 82.100.0.70] FastCGI: comm with server "/var/www/uzivatel/www.domena.xy.php5-fcgi" aborted: idle timeout (30 sec)
[Tue Jul 30 14:13:40 2013] [error] [client 82.100.0.70] FastCGI: incomplete headers (0 bytes) received from server "/var/www/uzivatel/www.domena.xy.php5-fcgi"
But PHP-FPM log is ok (it is generated in some miliseconds after the request):
- - 30/Jul/2013:14:13:10 +0200 "GET /index.php" 200 /var/www/uzivatel/webs/www.domena.xy/index.php 793.871 35072 37.79/30.23
There is the code 200 so the page seems to be created correctly but Apache behaves like no reply came from fastcgi server.
But the interesting part is, when I cut the page generation before , the apache returns it correctly to the client. But If I insert the <?php die(); ?>
after the tag, the same error happens.
Is there a way how can I debug communication between apache and the fastcgi server?
Here is the config (the same configuration is ok for another virtual webs):
<VirtualHost 1.2.3.4:80>
