I checked to make sure the lines were correct in maint.pl. I am reinstalling 4.0.1, again and will let you know how it goes.


OK, so it does dump core.

To get some more info about this, you need the core file *and* the
hobbitd binary that generated it. Then run

  $ gdb bin/hobbitd tmp/core
  [messages from gdb]
  gdb> bt

to load the core file and the hobbitd binary into gdb (the GNU
debugger), and the the "bt" command will provide a call trace of what
happened when the program crashed, that is the first piece of
information that is needed to find the bug.

Based on the core trace, I decided to remove all files from ~/server/tmp/. I do not think we had removed any files from running RC1,2,4-6 from '~/server/tmp/' so perhaps it was choking on something (hobbitd.chk)? It has been running clean for more than an hour. It typically dumps core before an hour has passed and the purple trends occur before an hour of running too. I did have to re-disable my disabled hosts of course. So far it looks good! Thanks for your help Henrik.
