Mod_security + mod_ruid2 working right?

I have installed mod_security with WAF rules, does this work with mod_ruid2 or not?

But I see this:

Is it working right or not? I want to test some bruteforce (enabled in comodo WAF) attacks.

I'm experiencing the same, how did you fix it?

Here example configuration: http://malware.expert/directadmin-modsecurity-configuration/

With this error: Audit log: Failed to unlock global mutex

Remove these (ifmodule) or comment, worked our server. (Custombuild 2.x / apache 2.4 / php 5.6 / ruid2 / modsecurity 2.9.1)
