 A concurrent-mode audit log is only useful for servers like Apache which is process-driven and has multiple processes that may change UID. LiteSpeed is event-driven, and as such, concurrent mode is not needed.

-The above error messages simply mean these variables are not supported by LSWS yet. They can be simply ignored.
+We try to keep LSWS compatible with the latest mod_security 2.5(and above) and gotroot rules. LSWS supports most of these rules. We attempt not to miss any really important features/rules used in the real world, and we regularly add support for more features based on our user feedback.  However, because of the complexity and fluctuating nature of these security rules, it is not possible to be 100% compatible with Apache at any one time.
-We will periodically review our mod_security engine and add new support to it. Stay tuned.
