I'll check these as soon as I can. ImageMagick isn't running according to top
when the lockup happens. Unfortunately it's not a few minute lockup. Under
Gnome it took at least a day or two to lock up. Under Fluxbox it takes several
days. In both cases it's happening only with an NWS radar map (the only maps
loaded other than the Tiger shapefiles). For a while, everything works as
expected. The radar map (a single radar since I'm zoomed into one state for
the most part) downloads and displays fine. Then one day I'll walk by the
machine and notice nothing is updating. The last message left in the status
bar is always referring to the NWS map when I see it locked up. Prior to this
everything (except a malfunctioning mouse) was working just fine. So the
system is completely junk free and up to date as far as I can tell. Xastir was
compiled from CVS.
