Is the initiator connected to the target running on the same box?
It looks like a command took too long. If a command takes longer than
the scsi command timeout (/sys/block/sdX/device/timeout) then the scsi
layer will try to abort it (if that fails reset the lun and if that
fails reset the host).

The initiator sends a iscsi nop as a ping every x seconds. If we do not
get a response we drop the sesison, try to relogin and retry the IO.

it looks like something happened to the target or connection. We were
not able to log back in after trying for 2 minutes
(node.session.replacement_timeout).
