etc. etc.
The server is up for 9 days now, and the apache error log is already 54 MB!

What does that error mean, and how do i fix it?

I use:

Linux version: Centos 4.3 64-bit, 2.6.16.17
Controlpanel: DirectAdmin

Apache version: Apache 2.0.58 Server
PHP version: 4.4.2
Zend Engine v1.3.0
Eaccelerator 0.9.3
DirectAdmin 1.27.1
Exim 4.60
MySQL 5.0.15
Named 9.2.4
ProFTPd 1.3.0rc2
vm-Pop3d 1.1.7f-DA-2
sshd

That error means that something inside of Apache/Php was trying to access memory it doesn't own, or there was a NULL pointer. There are many reasons on why that would happen, too many to tell what your exact problem is.

Do you know if it happens with all web pages or just php pages. Try removing the Eaccelerator, or any php modules and see if the problem continues. It is possible that Eaccelerator didn't get compiled correctly for your specific version of Apache/Php, do a make clean, redo the phpize and rebuild.

Thanks for the golden tip Tom. I disabled eaccelerator's caching of php scripts and optimization of php scripts.
Now i don't get any errors anymore. Though, i want eaccelerator running, any idea how to fix this eaccelerator problem?

 

[toml]

Try rebuilding it from scratch. It is version specific, so you can just update php and expect it to work. Since that it the problem, do as I said in my last post, a make clean, phpize and rebuild.
