Seems. that the problem is solved:

I found another thread: https://forums.fogproject.org/topic/6129/multicasting-stuck-on-starting-to-restore-image/36 where Tom gave the advice to remove the directory /opt/fog and start the installer again.
I did that, and after that i saw, that all the logfiles are created successfully. Then i cleared the old tasks

mysql -u root
use fog;
truncate multicastSessions;
truncate multicastSessionsAssoc;
truncate tasks;

after that i rebooted the server. Now newly created Multicasttasks work!

Thanks for your help!

My Multicast Tasks are starting now, but (i tried it 3 times with different images (all of them working with unicast)) they are not finishing => shall i open a new thread and mark this one as solved?

EDIT: Did other tests with multicast. At first i tried a small image (Zorin Linux - 8GB) it worked. After that i tried one of our Windows 10 Images again (~70GB) and it worked also.
So i mark this case with SOLVED!

@arnaudrigole
which fog version do you use? i had similar problems (see: https://forums.fogproject.org/topic/7414/multicast-not-starting/11). Do you have all the log files in /opt/fog/log?

@Tom-Elliott
Back again after upgrade:
i installed php7 and ran the installer with “php_ver=‘7.0’ php_verAdds=‘-7.0’ ./installfog.sh -y”
On my system there are still no logfiles, and multicast is not starting.
Trying to start FOGMulticastManager from commandline results in same error message:

As far i can see, there are still some php5 packages: (by fog installer?)

Yes the service are up, but there are still no log files.

My system is Ubuntu 14.04 LTS. The thread is for systemd startup, while my system uses sysvinit.
i have a strange behaviour now: After a system restart none of the FOG Service is running. When i try to start them with “service FOGMulticastManager start” i get an error. “service FOGMulticastManager restart” works!! After that the service seems to be running.

root@imaging:~# service FOGImageReplicator restart
[…] Restarting FOG Computer Imaging Solution: FOGImageReplicatorstart-stop-daemon: warning: failed to kill 2283: No such process
. ok

And there are no logfiles! (except Service Master Log)

@Tom-Elliott
The array_map() errors are gone now, but multicast is still not starting:

I can’t find any errors in apache logs now. I also wonder, why there is no multicast.log file? (i had a file, but this file was created during test with udp-sender on the console)
I cleared the folder /opt/fog/log and ran the installer again. After that the Service Master Logfile is created new, but all the other logfiles don’t exist:

in the Service Master Log i can see:
[05-19-16 4:40:11 am] FOGPingHosts child process (27579) exited with code 255.
[05-19-16 4:40:09 am] FOGTaskScheduler child process (27578) exited with code 255.
[05-19-16 4:40:07 am] FOGImageReplicator child process (27577) exited with code 255.
[05-19-16 4:40:05 am] FOGImageReplicator child process (27576) exited with code 255.
[05-19-16 4:40:03 am] FOGMulticastManager child process (27575) exited with code 255.

(is that OK?) - The timezone in the logfiles seems to be UTC, even if i correct the timezone settings in php.ini. The system time (date) also shows the correct time.

Any other debug options i could use?

@Sebastian-Roth
I mean, that multicast is not starting. In apache error log there are lines like “[client 10.2.2.83] PHP Warning: array_map(): An error occurred while invoking the map callback in /var/www/fog/lib/fog/fogcontroller.class.php on line 197”
There is another thread with similar error in logs:
https://forums.fogproject.org/topic/7412/problems-with-multicast-task/23

@Tom-Elliott
Did both, the error on the task management page is gone, but still the same error when trying to start multicast.

@Tom-Elliott
Did the Update (7701)

At the moment there is an error in management interface
