Hello @kurtc
were you able to resolve that issue?
I am experiencing similar issues: my FreeNAS system crashes completely when under heavy iSCSI (write) load. Today I even lost access to the system: no ssh, no web, no local console accessible. Fortunately iSCSI is still running so I have my VMs still up and running.
I am running 11.1 U4, maybe there's really a bug. I do not have a SLOG drive (yet :) )

No I was not able to resolve. I implemented an Optane slog to get over the issue as well. Since these are large backups running all day long it was eating my Intel 750's for lunch. I don't want to run a SLOG at all, but it just wouldn't stay running.
