Update conflict in MOSS 2007
An update conflict has occurred, and you must re-try this action. The object SPContentDatabase Name=WSS_Content_name Parent=SPDatabaseServiceInstance is being updated by domain\user, in the w3wp process, on machine server. View the tracing log for more information about the conflict. I was receiving this error in Central Admin when I was trying to increase the maximum number of sites in Manage Content Databases (/_admin/cntdbadm.aspx). I was unable to increase this number or delete site collections as well as a number of other events. The error condition seems to have affected deploying and retracting solutions as well. I resolved this by clearing the config cache followed by rebooting each WFE and index server. You may find the steps for clearing the config cache here: http://blogs.msdn.com/b/josrod/archive/2007/12/12/clear-the-sharepoint-configuration-cache-for-timer-job-and-psconfig-errors.aspx Due to a "stuck" Windows SharePoint Services Timer service on one of the WFEs, I rebooted all the front-end servers in the farm--one at a time to minimize client impact. I was also seeing Event ID 6398, Timer, An update conflict has occurred, and you must re-try this action.
