I have a SharePoint 2007 farm (w/ SP2, June cumulative update) hosting an Internet site and am seeing the nightly content deployment incremental job that moves content from our staging environment to production fail with the error below. When this happens the only way we know to resolve it is to manually run a full deployment. However the issue seems to come back again in a few days. Any advice on how to isolate the root cause of this problem and correct it?
