We tried your command with ImageMagick 6.2.7-7 Beta on a Fedora Core 5 system and valgrind found no complaints or memory leaks.

Add -limit memory 32 -limit map 64 to your command line (before your first image) and see if that helps.

Ok, add -debug cache to your command line. If that does not reveal anything interesting try -debug all or -debug trace.

You do not have enough free space in your /tmp directory. Find a path that has plenty of freespace (several gigabytes) and set the MAGICK_TMPDIR environment variable. Assume /data is writeable and has 10GB of free space:
  • export MAGICK_TMPDIR /data
    /opt/imagemagick/6.2.7-beta8/bin/convert srtm_ramp2.world.21600x10800.jpg -resize 2160x1080 srtm_ramp2.world.2160x1080.jpg
