Can you confirm that you are under an active attack? You may need to modify the SecWriteStateLimit settings if you are finding that you are having false positives. Since these log messages are generated from a directive and not a rule, we don't have any options for altering logging or response actions. It is hard coded to generate the alert for each thread that is is terminating. -- Ryan Barnett Senior Security Researcher Trustwave - SpiderLabs On 1/9/12 7:16 AM, "Anestis Bechtsoudis" <bec...@gm...> wrote: >Hello list, > >recently applied the SecWriteStateLimit workaround for slow HTTP read >DoS attack, as proposed from spiderlabs [1].
