Just to be sure, are you running the Ubuntu-provided package,
or<br>
something from another package repository? Which version of
Ubuntu?<br>
<br>
Running valgrind might produce similarly opaque results
without debug<br>
symbols (which you can enable if you build from source).</blockquote>
<div><br>
debug syms are available as separate debs.<br>
As an example, for Ubuntu, look here:<br>
<a moz-do-not-send="true"
href="https://wiki.kubuntu.org/DebuggingProgramCrash">https://wiki.kubuntu.org/DebuggingProgramCrash</a><br>
<br>
then look for installing {nut,libupsclient}-dbgsym and others
if needed otherwise...<br>

more involved, though (especially if you want to keep the
installed<br>
files in the same place) so I'd try that after Arjen's
suggestion with<br>
"-DDD".<br>

The only extra package I could find is the "dev" package. I'm not
sure if that contains debugging symbols.<br>
<br>
I'm running with the "-DDD" option now. It hasn't crashed over the
weekend, so we'll see how long it takes to crash now. I'm getting
source to try and rebuild it so that I can walk through in GDB if
necessary.<br>
<br>
Thanks.<br>
