(Sorry for the formatting on that last message, that was weird) Today I wanted to test the assertion that this is a NFS issue, since we all seem to be running NFS. I shut down my NFS daemon in rc.conf, configured the FreeBSD10 iSCSI ctld, rebooted, and then ran all my tests exclusively from the iSCSI connection to my FreeBSD-10 box. The only other thing I had active on the FreeBSD-10 box was a flood-ping so I could see if/when the problem occurred. I still had the problem. It triggered around 40 min into my iometer benchmark. Continued sporadically for a while, then settled down and didn't give me problems. That error behaviour isn't abnormal - I really need to push the SAN to put it's network into a 'dead and not coming back' mode. Any thoughts?
