[sheepdog-ng] main shutdown in sheep.log

[Valerio Pachera]

Hi all, I have a production cluster with 3 nodes.
There's only one guest running on the first node.
I noticed this in sheep .log of the first node

Nov 24 13:03:58   INFO [main] rx_main(859) req=0x7f9e4004cc00, fd=27, client=127.0.0.1:56179, op=SHUTDOWN, data=(null)

Nov 24 14:04:46   INFO [main] main(906) sheepdog daemon (version 0.9.0_327_gdc0496e) started

And very similar message on the other two nodes:

Nov 24 13:03:58   INFO [main] zk_leave(1036) leaving from cluster
Nov 24 14:04:37   INFO [main] md_add_disk(354) /mnt/sheep/0, vdisk nr 3523, total disk 1

Nov 24 14:04:38   INFO [main] main(906) sheepdog daemon (version 0.9.0_327_gdc0496e) started

What do you think it has happened?

What can cause these messages on all 3 nodes?
