I have a second ILM server for development and am having an issue with ILM not responding when running a full sync or preview on an object. I've reinstalled ILM and imported the server config from the main server that is running without issue. Also installed sp1 and I've copied over all of the extension files. If the Metaverse rules extension is enabled without the provisioning rules extension being enabled everything works fine. But once we enabled the provisioning extension we have to kill the miisserver.exe and restart the service. The server builds are pretty much the same the only difference is the remote sql server and instance.

Chimey,

This is probably due to a code flaw in your provisioning routing. Look for FOR or WHILE loops that don't terminate properly. It sounds like that is what is going on based on your description.
