Releasing semaphore 4 in request cleanup

Cause

After agent was upgraded on service nodes, and old instance has left running, therefore communication between management node and a service node breaks.

Resolution

Restart the following services on a problem service node (IP address should be gotten from the initial error):

 /etc/init.d/sw-cp-server stop
Stopping sw-cp-serverd:                                    [  OK  ]

/etc/init.d/sw-cp-server start
Starting sw-cp-serverd:                                    [  OK  ]

/etc/init.d/pem restart
Stopping pleskd:                                           [  OK  ]
Starting pleskd:                                           [  OK  ]

/etc/init.d/plesk-agent restart
Stopping agent.cgi:                                        [  OK  ]
Starting agent.cgi:                                        [  OK  ]
