Comment 2 Jason Dillaman 2021-03-03 01:23:04 UTC 
While the crash seems to be a definite bug, the proper way to add multiple IP addresses is to provide a comma-separated string when creating the gateway:

/iscsi-target.../gateways> create ansible.sample.com 1.2.3.4,1.2.3.5,1.2.3.6
Comment 23 Gopi 2021-06-23 06:07:38 UTC 
Working as expected.

/iscsi-target...-igw/gateways> create magna010 10.8.128.10,2620:52:0:880:225:90ff:fefc:252c
Adding gateway, sync'ing 0 disk(s) and 0 client(s)
ok
