apache and php5

[sputnik]

Hi,

my server runs openbsd 4.6 with apache unchrooted and php5 with extensions:

php5-bz2-5.2.10
php5-core-5.2.10
php5-gd-5.2.10-no_x11
php5-mbstring-5.2.10
php5-mcrypt-5.2.10
php5-mysql-5.2.10
php5-mysqli-5.2.10

I don't use the ports, i use precompiled packages. The problem is:
all php applications sometimes stops when executing some script, and gives no output, just a blank screen. For example phpmyadmin - sometimes works just fine, sometimes gives a blank screen when i'm inserting something in db table, exporting db to file, or doing something like that. Same with squirrelmail. Same with applications coded by my self. Sometimes it just needs to be refreshed, sometimes it needs to be refreshed few times, to get back interacting with application. I'm pretty sure this behaviour encounters only in 4.6 version. I had 4.5 before, and i still have one more box currently running 4.5 with apache+php5 working fine. I've tried to reinstall those packages, i've even tried to install them from ports. No result. This is really odd. Any ideas?

How exactly are you running PHP? You can use three methods (mod_php, FastCGI, and CGI).
Is there anything in your apache or messages logfile?

It's possible that PHP is crashing (thus giving no output).

Another possibility is that the script generated some PHP error and you have PHP configured in such a way that it will exit and display no warning message.
From memory the display_errors and error_reporting variables in your php.ini control this.

I'm runing php as apache module (mod_php). There's no need to turn error_reporting to E_ALL, 'cause i'm running simple php applications as squirrelmail, phpmyadmin... I was running those applications on openbsd 4.5, 4.4, 4.3 and so on...
If you've got few minutes, i can demonstrate it by giving you links to those applications ar even giving a shell...

simple php applications as squirrelmail, phpmyadmin

I would not call these "simple PHP applications" ...

Regardless, do you see anything in the logfiles?

[sputnik]

Apache log files? Nope, nothing unusual, neither custom or error log...

You have this lines?:
AddType application/x-httpd-php5 .php .htm .html

check your php config ans see Apache logs for more information.

Yes, i have those lines, and i have default php.ini. Apache logs doesn't show any errors.

I just found this page with google.
I have the exact same problem on two servers.

OpenBSD 4.6 + Squirrelmail on one server.
OpenBSD 4.6 + Cacti on one server.

The symptoms are the same on both servers, the exact same as sputnik described.

I can see in the logs for Cacti that it segfaults every time the page goes blank.

A solution for this would be much appreciated.

Solved it!

# vi /var/www/conf/php.ini
change: suhosin.session.encrypt = off
# apachectl restart

This solved my problem on both servers. Hopefully 4.7 will have fixed this.

This is fixed in the 4.6 stable ports tree.

Yep, Botanic's proposed solution helped. Thank you!
