This configuration option may be supplied to specify the maximum number of audit log files that will be allowed -- when this threshold is reached then an error occurs and all auditing will fail.
For example, with this value set to "3", audit.log, audit.log.0 and audit.log.1 will be created according to the maximum log size value. If another audit log rollover is triggered then all audit operations will fail until one of the rollover files is removed.
This value is mutually exclusive with the deletion threshold -- the smallest value of the two will take effect.
