--- Comment #14 from Julien Cigar <julien@perdition.city> ---
This is also what I thought at first, but there is no error messages relate=
d to
the network interfaces in the logs, and all Ierrs, Idrop, and Coll counters=
 are
zeros.

There is a dedicated interface for the iSCSI traffic which I turned on/off
quite a lot to test a failover script, and the symptoms are exactly the ones
described by Ben Rubson in the post above (altough I only have 4 disks in
total).

One more thing, I'm managing everything with SaltStack and in some cases ct=
ld
on the target and iscsid on the initiator are restarted at the same time, c=
ould
it be because of that?

I forgot to paste my rc.conf filers, but I don't think there is something w=
rong
