Lukas, I suspect we have an issue in inventory (or two) - when I run inventory as is with h2db, it works, but may or may not contribute (a lot) to the growth of the heap as seen in the "Hawkular-services and memory" thread. - When I try to run against postgres 9.5, the WildFly of the platform never is available inside inventory. I see tables in postgres, but the WF never shows. Also later on I got below error I am also a bit puzzled, that using postgres starts of a c3p0 connection pool instead of using what is already present in WildFly hawkular_1 | 20:11:37,309 WARN
