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.

It's an error with the time clock on your computer, has nothing to do with ZFS, iSCSI, etc.

Try updating your MB's BIOS. Or post the make/model and we might be of more help. In any case it's nothing to worry about if the clock is still correct.

Really, it is a clock issue? The reason I guessed about ZFS or iSCSI was that I had a pci-e card with two drives fail and cause a ZFS I/O panic a few days before this. The model motherboard is ASUS P5BV-C –  Jeremy Hajek Oct 14 '10 at 18:10
    
There aren't any other reports of people having problems with that board, but the error is definitely clock related (specifically making adjustments to the clock). I suppose it's remotely possible the failed card did something to the MB. –  Chris S Oct 14 '10 at 18:27
    
I adjusted the time on the system using the date command. But t_delta is still printing too long and also too short errors. This is a production server so I have to wait for the weekend to take it down to check the time and date in the BIOS. –  Jeremy Hajek Oct 14 '10 at 22:28
