Errors in Universe log of node1:

| 2021-03-15 08:24:37 |ERROR|X|IO |pid=21476.18928| owls_api_exchanger_create | Error 200 connecting to node <node2> port 10700
| 2021-03-15 08:27:07 |ERROR|X|IO |pid=21476.18928| owls_api_exchanger_create | Error 200 connecting to node <node2> port 10700

E.g. case:

In Node1 there was an uproc with dependency with uproc of node node2, but now this uproc is removed and there is no other reference in node1 with node2.

Node1 is trying to connect with not existing node2.

Cause

The reason of the error messages appearance is because the node id records still exist in the exchanger data files u_fecl60 and u_fecd60.

Environment

Release : 6.x

Component : DOLLAR UNIVERSE

Resolution

To get rid of the messages reinitialize the files u_fecl60 and u_fecd60 and errors should disappear.
