# Logging With Multiple Processes

If you have multiple applications that all log to the same file, it is often
desirable that the file that these applications write to will roll over when
required.  In order for that to happen, Log4cxx supplies a
`MultiprocessRollingFileAppender` that will check the size of the file when
writing to the file and roll it over appropriately.

This is an optional feature, and thus must be explicitly enabled when building
Log4cxx.  This feature is also only supported on Linux at the moment.
Because this feature is non-standard, it may not work properly in all
circumstances.
