Exception thrown in QuickLinkServlet

I find several execptions and I get some reports of updates that are failing but I am not sure these are related:

2005-05-18 15:01:28,812 WARN [atlassian.jira.servlet.QuickLinkServlet] Error retrieving ChangeItems to search for moved issues. If using MSSQL, this is probably related to JRA-5067.
