Chapter 1 What’s New for FortiOS 5.0 : New features in FortiOS 5.0 Patch 6 : Miglogd Child Processes
  
Miglogd Child Processes
The number of miglogd child processes can now be configured directly through CLI to a value between 0-15, in order to keep up with logging requirements. The default number of child processes is 8.
Log messages are not lost if the number of child processes is decreased.
Syntax
config system global
set miglogd-children <integer>
end
 
Increasing the number of child processes may affect a FortiGate unit’s performance.
