Constant error is crashing site!!!

One of my sites is getting a constant error in the modules/error_log file

the error is writing constantly and filling the file to 2GB in a day...

As soon as the error_log hits 2GB, it can no longer be written to and then all the modules on the site crash. They just show an error page with text saying the site is being repaired...

This is the 5 lines of error code that are being writtne over and over again non stop...

first and foremost, you need to get your server configured correctly .secondly, your error_log should not be hitting 2GB, and you should have something written that would purge those error_logs or archive them. 1024 is apache's max setting for error_logs

you are missing dynamic library links, which is what the error is you posted here.

My host have told me they need to rebuild PHP on my server.

Dont know what was changed to make this happen which it is a lot at the moment...

how can I set it to purge the error_log?

Thanks - Tim

The problem is in the php.ini, there is a directive to load these dynamic library which was not installed. You can install these libraries or you can remove those directives in your php.ini

Thanks. Where do I find the php.ini file that needs editing?

Thanks - Tim

The php.ini can be anywhere.

Mostly it will be in the following paths.

/etc/php.ini

/usr/local/lib/php.ini

host rebuilt php, then did something to apache that they said fixed it.

Still happening though and site constantly crashing.

CHAT seems to be trigering the errors.

This is the only one now, but still getting 2GB a day of this...

Common problem when someone upgrade the php with new PHP API (the number 2006...) and forget to compile or add the modules it should have.

Make sure your host helps you with the compiling of a new php with the extensions you need, for example the ffmepg extension you are missing now.

Locate your php.ini by logging in to your shell and type as root: find / -name php.ini and edit it and remove ffmpeg and restart your webserver. Add the extension again after you got help with rebuilding your php with additional ffmpeg extension.
