Specifies the maximum number of characters that the logger daemon processes from the message queue before discarding all remaining messages in the queue.
The message that causes the total number of characters to exceed the maximum is not truncated.
All discarded messages are summarized by the logging system with a single log entry detailing the number of discarded messages and their total size. When the queue empties, the logger is reset and subsequent messages are again logged.
The purpose of this setting is to avoid a situation where logging can itself prevent recovery from a failing condition, for example by contributing to timing issues.
Logging occurs on a dedicated low-priority thread to further reduce its impact on the critical portions of the system.
Optional.
Possible values are positive integers or zero (0). Zero implies no limit.
Default is 0
