When I check phd status:
OptiPlex-7020:/var/www/phabricator$ ./bin/phd status
Log Daemon Host Overseer Started Class Arguments

OptiPlex-7020 2765 Jun 8 2017, 12:30:07 AM PhabricatorRepositoryPullLocalDaemon

but I want stop phd Daemon. I had a problem:

OptiPlex-7020:/var/www/phabricator$ ./bin/phd stop
There are processes running that look like Phabricator daemons but have no corresponding PID files:
3441 php ./phd-daemon
Stop these processes by re-running this command with the --force parameter.

if I start again ,it would be like that:

OptiPlex-7020:/var/www/phabricator$ ./bin/phd restart
There are no running Phabricator daemons.
Freeing active task leases...
Freed 0 task lease(s).

(Pool: 1) PhabricatorRepositoryPullLocalDaemon
(Pool: 1) PhabricatorTriggerDaemon
(Pool: 4) PhabricatorTaskmasterDaemon

Done.

I tried to stop a Daemon ;
OptiPlex-7020:/var/www/phabricator$ ./bin/phd stop 3441
There are no running Phabricator daemons.

what should I do ? Have you ever had a similar problem?
