I have noticed such problems before - the depmod code just loads whole module files into memory. The situation is especially bad when module-init-tools is configured with --enable-zlib - in this case memory for all module files is allocated with malloc(). (Without --enable-zlib depmod just mmaps all module files, which at least does not eat swap, and probably does not bring unused pages into memory.) I have made some patches to module-init-tools - unfortunately, they probably don't apply to the current version (they were based on v3.3-pre4): git://git.altlinux.org/people/vsu/packages/module-init-tools.git (release-module-data branch) http://git.altlinux.org/people/vsu/packages/?p=module-init-tools.git;a=shortlog;h=release-module-data
