I have a node that from some reason change state to "Down" evert few minutes.
When I change it with scontrol to "resume" its ok until Down again.
In the slurm server log I can see error:
"agent/is_node_resp: node:myName1 RPC:REQUEST_PING : Can't find an address, check slurm.conf"

Now, The error message seems kind of straight forward but I can't find the problem.
* The node is up and answer to ping from the slurm server.
* The slurm deamon on the node is up and running.
* There isn't any error on the node itself.
* There are more node, configure the same (except from the ip address) that are Ok.
* running "scontrol update state=eesume nodename"myNode" fix the problem for a short time
* restarting slurm deamon on node also fix this for a short time

Any idea what more I can check to resolve this?
