That message usually says that the target is either slow or lies in
how many concurrent requests it can handle. It may stall the iscsi
connection, but it shouldn't make the machine non-responsive. I haven't
seen it forever, but I mostly test the in-kernel initiator against
Linux, FreeBSD (FreeNAS) and istgt.

You run -current on the VM but have a netbsd-7 image attached?

In my experience net/istgt is a much better iscsi target. No idea wether
it builds or runs under MacOS.

Hmm. iscsi-initiator and iscsi-target are both in /usr/sbin.

iscsid and iscsictl are in /sbin.
