This is a continuation of Troubleshooting Node down Scenarios in Azure Service Fabric here.
Check the Network connectivity between the nodes:
If request times out.
Check if any NSG blocking the connectivity.
Node-to-Node communication failure due to any of the below reason could lead to Node down issue.
Node1 is not able to establish lease with a Neighboring node2 could cause node1 to do down.
From the SF traces:
For example in the logs we see a node with Node ID “e4eac25286f23859b79b5483964ab0c8” (Node1) failed to establish lease with a node with Node ID “c196867202638ea43655614031736e9” (Node2)–
Now the focus should be on the node with which the lease connectivity is failing rather than the node which is down.
From above traces, we get the Error code: c0000017
To understand what this Error code means, please download Microsoft Error Lookup Tool.
And execute the exe by passing error code as Parameter:
Restart the node (Node2) which could free up the Virtual Memory and start establishing the lease with Node1 to bring the Node1 Up.
