Problems since upgrade neo4j to 3.5.1

[tomswinkels]

Hi,

Since i upgrade neo4j from 3.4 to 3.5.1 i have problems with long running queries.

What i see is that there even running long system queries.

Like, CALL dbms.cluster.role() but i don't have a cluster.

Hi Tom,

Are you using Halin anywhere with Neo4j?

Those queries you see running look like the kinds of things Halin would be running in the background to help monitor your Neo4j instance. If this is the case, they're nothing to be concerned about I don't think. If this isn't the case and you're not using Halin, please provide some more information.

Did you try if 3.5.2 is better? If possible close Neo4j Browser it might send some blocking statements. (queryJmx)
