Recently we started seeing this error when Manifold CF starts up. We had been running Manifold CF with many web connectors and a few RSS feeds for a while and it had been working fine. The server got rebooted and since then we started seeing this error. I'm not sure exactly what changed. Any ideas as to where to start looking and how to fix this?
Thanks! Mike Initial repository connections already created.
