which causes loading system and slowing down of "Nova_create_and_delete_secgroups" test.
It was found that two nodes which weren't included in the cluster and weren't discovered by Fuel
but resided in the lab environment constantly generated error messages: "Could not find kernel images".
After that nodes were powered off the tftp processes released.
Conclusion: expected behavior - cluster shouldn't be affected by some nodes which aren't included into the cluster. Undiscovered nodes shouldn't create pefromance impact on the Fuel master node.
During Rally test suite run on big scale.
On Fuel master node where discovered large number of tftp processes:
[root@fuel ~]# ps auxwwwwf | grep in.tftp | wc -l
1721
