I've been running Confluence for over a year now, and all of a sudden we can't get into it due the the following error. we are not running it in a cluster environment, just a single install on our server. We really need to get into our system and are stomped on why this is happening. We have not made any changes to install or ran any updates.
Non Clustered Confluence: Database is being updated by another Confluence instance. Please see http://confluence.atlassian.com/x/mwiyCg for more details. FATAL
