Hi Lachlan,
Thanks for the replay. I am trying to find more Ideas for this problem. May be
some system or strange communication problem.
As for your suggestion:

The problem is that I don't see any other error and the node is up and running
without any error.
The communication looks good with good ping but still it looks like the server
can't find it (And it happen every two minute, always).
Thanks for your ideas,
Roy.

Hello,
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?
Here's a quick top of my head checklist:
Check that it's in /etc/hosts
Check the slurmd logs
Make sure there is enough disk space
Make sure that it's datetime is synchronized with the others
cheers
