Multicast does not work anymore

we successfully imaged some computers using multicast, but now it does not work anymore. I added 5 computers to a install group and asked to deploy via multicast.
Multicastmanager seems to be running:
# systemctl status FOGMulticastManager -l ● FOGMulticastManager.service - FOGMulticastManager Loaded: loaded (/lib/systemd/system/FOGMulticastManager.service; enabled; vendor preset: enabled) Active: active (running) since Mon 2017-09-25 13:35:31 CEST; 2min 57s ago Main PID: 31574 (FOGMulticastMan) Tasks: 4 (limit: 4915) CGroup: /system.slice/FOGMulticastManager.service ├─31574 /usr/bin/php -q /opt/fog/service/FOGMulticastManager/FOGMulticastManager & ├─31575 /usr/bin/php -q /opt/fog/service/FOGMulticastManager/FOGMulticastManager & ├─31967 sh -c /usr/local/sbin/udp-sender --interface ens33 --min-receivers 5 --max-wait 600 --portbase 54196 --full-duplex --ttl 32 --nokb └─31971 /usr/local/sbin/udp-sender --interface ens33 --min-receivers 5 --max-wait 600 --portbase 54196 --full-duplex --ttl 32 --nokbd --no Sep 25 13:35:31 debian-linux systemd: Started FOGMulticastManager.
Question for me is now: Before starting this multicast session with 5 hosts, I saw just:
Tasks: 2. Why are there 4 now? And when there were 2: I have had no active tasks in the tasklist.
FOG Configuration Page->Log Viewer-> Multicast just shows:
[09-25-17 1:39:53 pm] | Task (16) Multi-Cast Task is already running with pid: 31967. [09-25-17 1:40:03 pm] | Task (16) Multi-Cast Task is already running with pid: 31967. [09-25-17 1:40:13 pm] | Task (16) Multi-Cast Task is already running with pid: 31967.
The 5 clients simply stop at the Partclone Screen, where it says: Starting to restore… and the Image location is …
Any help is appreciated!
@tywyn That’s the “processes” (called tasks in systemctl) that are running for the service. Those, themselves, are not tasks in the sense as you’re referring to them.

@Tom-Elliott You said, that you see just one task. What does the
Tasks: 4 (limit: 4915)mean?

I only see one task.
systemctl status FOGMulticastManager -lis outputting all things related to that call.
php -q /opt/fog/service/FOGMulticastManager/FOGMulticastManager &lines appears that it started once and restarted it again.
sh -c /usr/local/sbin/udp-senderis the process starting the real multicast task itself.
/usr/local/udp-senderis the actually running command.
