To improve logging performance the Wrapper writes to its log file
without flushing after each write. The performance improvement
for large quantities of output can be significant but it comes at
the cost of a possible loss of log data should the Wrapper process
or system crash. This property controls the maximum amount of time,
in seconds, that the Wrapper will allow the log file to remain in
an unflushed state. A value of 0 will force the Wrapper to flush
the log file after each and every write. Defaults to 1.
Example:
wrapper.logfile.inactivity.timeout=1
NOTE
This property was implemented in version 3.2.0. Prior versions
flushed the log file after each any every log entry.
