Deleting a zvol caused Freenas 11.3 to freeze and reboot

Using:
FreeBSD freenas.mclean.harvard.edu 11.3-RELEASE-p6 FreeBSD 11.3-RELEASE-p6 #0 r325575+d5b100edfcb(HEAD): Fri Feb 21 18:53:26 UTC 2020 root@tnbuild02.tn.ixsystems.com:/freenas-releng/freenas/_BE/objs/freenas-releng/freenas/_BE/os/sys/FreeNAS.amd64 amd64

I created a zvol, shared it via iSCSI. Played with it for a bit, stored some files. Unmounted it. I then went to delete the zvol -- but I didn't unshare it first or touch the iSCSI configuration in any way. Freenas immediately crashed and rebooted.

I can't seem to reproduce this, but if anyone would like to help investigate or look at logs, let me know.

Also, I'm now unable to delete the target from Sharing / iSCSI / Targets. I do delete/confirm/delete... and nothing happens.

The unexpected reboot happened to me too doing the same exact thing with iscsi. 11.3-U1. Ping me if you need logs or anything.

I was able to delete the Zvol after deleting the iSCSI entries in Targets and Extents.
