modsec - ModSecurity: Rule processing failed

Hello,

I just update my modsec rules with the last release of Atomic's Delayed rules, and now I see many errors in my httpd error.log files:

"ModSecurity: Rule processing failed"

What exactly means this message? Does the client still get the page/file requested or see an error message?
Why does it happen?

The strangest thing is that it usually happens when file requested are CSS or image files (jpg/png...).

Thanks for your help and advice on this!

Could be that, 2.5.6 is probably 2 years old by now. Current version is 2.5.12

Yeah thats a very old version of modsec, and that error definitely occurred with older versions. Not to mention all versions prior to 2.5.10 had a vulnerability, so you should definitely upgrade.

I juste updated to the last version available on ART, and now I've this error all the time:

ModSecurity: Unable to retrieve collection (name "global", key "global"). Use SecDataDir to define data directory first.

Anybody knows how I can solve this problem?

I finally found the solution here:
http://www.atomicorp.com/forum/viewtopic.php?f=3&t=3679

"I have added SecDataDir /var/asl/data/msa in the config /etc/httpd/modsecurity.d/modsecurity_crs_10_config.conf too."

Make sure you have modsecurity setup per the wiki article:

Yeeep, you're right, everything's written in the wiki.

I've one last question:
The Rule Updater is only available to ASL customer, right?
As I don't understand where to get a username/password.

Thanks.
