Hi,
I've got a FreeBSD 10.1-RELEASE box running with iscsi on top of ZFS. I've =
had some major issues with it where it would stop processing traffic for a =
minute or two, but that's 'fixed' by disabling TSO. I do have frequent iscs=
i errors, which are luckily fixed on the iscsi layer, but they do cause an =
occasional errormessage on both the iscsi client and server. Also, I see in=
put errors on the FreeBSD server, but I'm unable to find out what those are=
. I do see a relation between iscsi-errormessages and the number of etherne=
t inputerrors on the server.
I saw this message [1] which made me have a look at `vmstat -z`, and that s=
hows me the following:
vmstat -z | head -n 1; vmstat -z | sort -k 6 -t , | tail -10 ITEM =

I am using jumboframes. Could it be that the inputerrors AND my frequent hi=
ckups come from all those failures to allocate 9k jumbo mbufs? And can I in=
crease the in [1] mentioned sysctls at will?
Thanks
