INTEGER, read-only.

Deprecated. Available inpassmissdeliverlogerror

The number of WAF rules that failed to evaluate.

This variable is incremented by the WAF each time a rule fails. This may happen, for example, if available memory is exhausted during processing of the rule.

In the waf_debug_log subroutine, the value of this variable will reflect the number of rule failures so far, and not whether any individual rule failed.
