Task Flows in Classic HFM 188.8.131.52 are interesting beasts. If your clients rely on them to run consolidation packages like ours do, they could be in some trouble. If there is any drop in communication between HFM and Shared Services, your results will not be as desired.Consolidation packages that should have to run 12-16 hours stopped unexpectedly after a few hours. Looking through the logs, we found the tasks were unsuccessful. Fortunately, an email was sent out to that effect, so the issue was noticed by the administrators. It was a fluke - there was an invalid SSO token, caused by a time stamp being 8 hours off on one of the load balancers for a few minutes. That was enough to derail ALL the tasks running at that time.
