incomplete output on kill signal

[Jozsef Fleischer]

When the fatrace process is killed with KILL signal, then the last line in the file output is incomplete:

root@hostname-1:~# ps -ef | grep fatrace
root 19127 16110 0 14:42 pts/0 00:00:00 fatrace -c -o /var/tmp/fatrace_output.txt -f W
root 20245 19795 0 14:42 pts/1 00:00:00 grep --color=auto fatrace
root@hostname-1:~# kill -9 19127
root@hostname-1:~# tail -3 /var/tmp/fatrace_output.txt
rsyslogd(21480): W /var/log/heat/heat-api.log
apache2(4389): W /var/log/apache2/cinder-api.access.log
ruby(7036): W /var/log/mroot@hostname-1:~#

The last line is not terminated with NL.

This isn't something that can be "fixed" reliably -- there's no escaping or controlling a SIGKILL. If you want to gracefully shut down fatrace, then use SIGTERM or SIGINT (i. e. Control-C).
