Description

On user found a case where generation is never ending, with the following stack trace:

We don't know the cause for now, but there is relay, and there was a lot of updates in the node/releay topologie. So Rudder must have badly updated something somewhere, and now there is an infinite loop when trying to generate policies.

The problem was seens in 4.0.0, but most likelly already exists in previous versions.

So it happens that the node that is leading to the error (7357f552-34ee-4b8d-9fa9-54854bbdece0) is removed:

curl -k -H "X-API-Token: xxxxxxx"  https://yourserver/rudder/api/latest/nodes/7357f552-34ee-4b8d-9fa9-54854bbdece0
{"action": "nodeDetails","id": "7357f552-34ee-4b8d-9fa9-54854bbdece0","result": "success","data": {"nodes": [
{  "id": "7357f552-34ee-4b8d-9fa9-54854bbdece0" 
  , "hostname": "relay.bal.local" 
  , "status": "removed" 
  , "policyServerId": "root" 
  ...
}

Fully removing by hand the node with the following LDAP command solved the generation problem:

ldapdelete -x -r -D "cn=Manager,cn=rudder-configuration" -W "nodeId=7357f552-34ee-4b8d-9fa9-54854bbdece0,ou=Nodes,ou=Removed Inventories,ou=Inventories,cn=rudder-configuration"

It is not clear at all why the node was taken into accound for policy generation, nor why there was a stack overflow.

One clue is that node : "relay.bal.local" does exsist but with a different id
