I am using FreeNas 0.7.1 (FreeBSD 7.2-release-p6) Recently I have been getting a series of these error messages to the console. I am using ZFS pools mirrored on the FreeNAS system, and they report as healthy and in good status.
I think this error message is related to the FreeBSD underneath. The ZFSpools are iscsi targets for a VMWare installation over Gigabit network. Is the delta_t they are referring to talking about a potential time out for packets over iSCSI? Has anyone experienced this error message? I have attached an image below.
