Are you running the CVS version of xastir?  When was the last time you built
it?

I routinely run xastir with as many as a hundred shapefiles loaded at any 
time, and rarely see it use more than about 16MB.  Right now I've got all
the tiger shapefiles for my state and a dozen or more other maps displayed,
and my resident memory usage is 9MB after 21 hours uptime.  There was a time 
when there was a serious memory leak in dbfawk, but that was months ago.

There could be a new memory leak in some aspect.  How many shapefiles do
you load?  Do you use dbfawk or do you configure with --disable-dbfawk?
Have you tried running with a lighter-weight desktop than KDE?  Is the
behavior the same?
