PBS not running

when I run the command “sudo /etc/init.d/pbs start” it returns:

Starting PBS
PBS comm
/opt/pbs/sbin/pbs_comm ready (pid=15178), Proxy Name:pbs-virtualbox:17001, Threads:4
PBS mom
PBS scheduler already running.
/opt/pbs/sbin/pbs_ds_systemd: 43: [: xrunning: unexpected operator
Connecting to PBS dataservice...connected to PBS dataservice@pbs-virtualbox
PBS server

But the command “sudo /etc/init.d/pbs status” returns:

pbs_server is not running
pbs_mom is not running
pbs_sched is pid 12122
pbs_comm is not running

Can you please tell me what is the problem ?

Thank a lot for your help
