A directory, a broken symbolic link or an unreadable file in the spool directory var/mkeventd/spool made the Event Console restart its event server every two seconds, and a FIFO there made it hang. A spool file it couldn't remove was processed again with each restart.

Now it only reads regular files there and warns once about anything else. It removes a file before processing it. A file it can't read or remove, or one bigger than 16 MiB, is renamed to .<name>.unreadable if possible, otherwise skipped. Either way, it logs an error in var/log/mkeventd.log.
