Our SharePoint 2010 publishing site keeps creating 1000's of duplicate heading nodes in various sub site quick launch menus. This then causes the site to become very slow until it no longer functions.
When and where this happens is very random. Currently we fix this issue using powershell to delete the duplicate nodes.
We cant seem to narrow down what is causing the issue, although I suspect it has something to do with quick launch headings been added by our publishers.
If anyone has experienced this or has any ideas of what we can do to fix this issue it would be greatly appreciated.
Thanks Mark
