com.atlassian.confluence.extra.webdav.servlet.ConfluenceWebdavServlet "Unexpected error" org.apache.jackrabbit.webdav.DavException: Precondition Failed

We have been getting a lot of these exceptions lately. I looked at our source code, and it seems to be related to the amount of locks returned by the servlet, although very inexplicit.

Have you seen these from other customers, and do you know the cause? We use office-connector v.1.18

We also get a lot of these issues. We had them in Confluence 3.5.13 and also in latest 4.3.3. I do not exactly know what causes this issue but I think it may also be related to some files. To me it seems that not all files are affected but some. The issue we get is:

I get these since upgrading to Confluence 5.4.3. The users say they are not getting errors in the UI, but it's making the log totally unreadable.

same here, we started to get these after the upgrade to 5.4.3

Same here. We are running Confluence 6.1.0
