Hi guys We are running into a strange situation where we have a few processes under Metrics->Running that do not complete for multiple days.  I checked the logs and can only see the below error that seem to point to something timing out.  We literally have no other errors in the logs. Jan 30 16:02:17.977 - ERROR - Connector: (1/35) java.util.concurrent.TimeoutException: Futures timed out after [7 days] Jan 30 16:02:17.977 - ERROR - Connector: (2/35) #011at scala.concurrent.impl.Promise$DefaultPromise.ready(Promise.scala:219) Jan 30 16:02:17.977 -

Figure 2: Sub-flow that retrieves the logged in user account (as seen in Figure 1). Figure 3: Flow that checks whether a case is assigned to a logged in user. Any advice will be greatly appreciated as always. Gustav
