No .log files. Something happened, either at 06:15 or between 06:15 and 
06:20.

1: next time, show "date; ls -la". This adds current local time, and last 
directory change.
2: look at "df", perhaps you have disk full
3: look at your mail. Errors and warnings should arrive there.  No, "mrtg 
 >/dev/null 2>&1" in your crontab is not a good idea.
