Manasa let me know that the ELOG was down, and that she used the normal restart procedure, but then all entries were gone. 

This is because the ELOG has been moved on nodus, so going to the old place and running the restart script starts up the old dysfunctional ELOG installation. 

The proper place to restart the ELOG is now nodus:/export/home/elog/start-elog.csh

I'm updating the relevant 40m wiki page now.
