ID: 8673 Title: Do not swallow I/O errors when communicating to mkeventd Component: Livestatus Level: 1 Class: Bug Fix Version: 1.4.0i3 Previously, I/O errors caused by communicating with mkeventd were silently swallowed by the Livestatus interface, returning just an empty result. Now you get an appropriate error when using the "fixed16" response header.
