Hello i have never seen that before,
but i just created a new synciq policy, the first sync works well but after the initial sync the second one crash all the time...
When i check on the job summary i can see that the target host is localhost... I don't understand why
Can you provide some information form logs?
# tail -20 /var/log/isi_migrate.log
Also what is gateway priority set for management & synciq.
Try setting gateway priority 1 for synciq using network and then try.
