Hello Dear users of Ganglia,

We have around 20 clusters in our organization all over the world. All are standardized to Centos 6.6.
We have installed Ganglia 3.7.2 on all.  The data are collected by the gmetad server.
Most of them were installed without any problems. Owe faced an issue on two of them, very strange issue.

All of the hosts in cluster are up, calculates without any problems. But on ganglia only master node is up. Rest of the nodes are down for Ganglia.
Some of nodes are coming up every 15 minutes for 1 minute (see attachment).
Of course I've check every conf files and they looks OK. All services was restarted and running. No crontab present on nodes.

I would be grateful for any hints.

Best Regards
