I'm running a bit different "test" now and I'm getting host resets on 
open-iscsi side every few minutes:

  connection3:0: iscsi: detected conn error (1011)
iscsi: host reset succeeded


The "test" is using DRBD over a slow link.
In such case (background synchronization running over a slow link), for 
tgtd, DRBD device for look like one that returns reads fast (say, 50 
MB/s), but any write, even small, can potentially wait several seconds 
to complete (with average speed of about 200 kB/s and long delays).

How can I check what causes these resets?
