[Valerio Pachera]

There might have been problem since before that I dodn't notice because I
have lot's of

Mar 26 08:34:38 [gway 25517] wait_forward_request(166) poll timeout 1

on the node "sheepdog004" (id 2) since 26 Mar.
Collie vdi list was not giving error so I didn't look or noticed that data
was not distributed on the nodes.
