Bug ID: 1292027
Summary: Stopping pmcd takes a long time
Product: Fedora
Version: 23
Component: pcp
Assignee: nathans@xxxxxxxxxx
Reporter: myllynen@xxxxxxxxxx
QA Contact: extras-qa@xxxxxxxxxxxxxxxxx

Description of problem:
localhost:~# date ; time systemctl start pmcd.service ; date ;
Wed Dec 16 11:23:21 EET 2015
systemctl start pmcd.service 0.00s user 0.01s system 2% cpu 0.457 total
Wed Dec 16 11:23:22 EET 2015
localhost:~# date ; time systemctl stop pmcd.service ; date ;
Wed Dec 16 11:23:25 EET 2015
systemctl stop pmcd.service 0.01s user 0.01s system 0% cpu 3.349 total
Wed Dec 16 11:23:29 EET 2015
localhost:~#
While 4 seconds might not sound like "a long time" it's actually more than half
of the time spent when shutting down all the services running on a default
Fedora installation.
IOW, after "poweroff" on Fedora the time to shutdown the system without pmcd is
~1-2 seconds. With pmcd in play the time is ~5-6 seconds.
