Were you heavily loading a software-based iscsi setup (client and target)?

I was considering a similar idea of using swap over nfs but it has been
reported as having problems under load in the past.

With just straightup sequential ops (e.g. shred a large file) I have had
glusterfs lock up where the only recovery is a client reboot. Same for
nbd (network block device) and nfs in the 4.14 kernels.

So I wonder about software-based iscsi reliability with a heavy load.
