Older versions of mythfilldatabase used a huge amount of memory. If you 
have a 4GB machine it could be swapping extensively. I have a script 
that deals with that problem by splitting the run into separate pieces, 
a few days at a time instead of the full 14 days in one load. The change 
to fix this was made in February 2020. fixes/31 and later do not have 
this problem.
