When updating the central site of a distributed setup to Check_MK 1.4.* and leaving the slave sites on older versions the other sites were marked as dead sites while rendering the page.
This issue was caused by the tactical overview snapin that tried to calculate the numbers for the "Events" of the Event Console. The slave sites using older Check_MK versions do not support that kind of query. Once this query is made the sites are marked as dead and are also not shown correctly in the master control and site status snapin.
A possible workaround would be to update all involved sites to Check_MK 1.4.
Also affected are sites that use the Nagios core and have the Event Console disabled. They still report an error to the GUI. This will be fixed soon.
