I can confirm the bug. Emerge starts @preserved-rebuild by allocating over 400MB of memory and keeps it allocated throughout the installation. I have 1GB of RAM and 512MB of swap so I'm fine unless emerge tries to install something memory hungry (e.g. dev-libs/boost) but systems with less RAM will run into trouble. I have absolutely no idea what kind of data you keep in that memory once the dependency tree is computed but I'm quite sure you don't need most of it anymore. portageq match / "" | wc -l 1466 emerge --info Portage 2.2_rc40 (default/linux/x86/2008.0/desktop, gcc-4.2.4, glibc-2.10.1-r0, 2.6.30-gentoo-r5 i686) ================================================================= System uname: Linux-2.6.30-gentoo-r5-i686-Genuine_Intel-R-_CPU_T2300_@_1.66GHz-with-gentoo-2.0.1 Timestamp of tree: Sun, 30 Aug 2009 13:45:02 +0000 ccache version 2.4 [enabled] app-shells/bash: 4.0_p28 dev-java/java-config: 1.3.7-r1, 2.1.9 dev-lang/python: 2.4.6, 2.5.4-r3, 2.6.2-r1, 3.1.1 dev-python/pycrypto: 2.0.1-r8 dev-util/ccache: 2.4-r8 dev-util/cmake: 2.6.4-r2 sys-apps/baselayout: 2.0.1 sys-apps/openrc: 0.4.3-r3 sys-apps/sandbox: 2.1 sys-devel/autoconf: 2.13, 2.63-r1 sys-devel/automake: 1.5, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10.2, 1.11 sys-devel/binutils: 2.19.1-r1 sys-devel/gcc-config: 1.4.1 sys-devel/libtool: 2.2.6a virtual/os-headers: 2.6.30-r1 ACCEPT_KEYWORDS="x86 ~x86" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=prescott -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/share/config /var/lib/hsqldb" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/php/apache2-php5/ext-active/ /etc/php/cgi-php5/ext-active/ /etc/php/cli-php5/ext-active/ /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo /etc/texmf/language.dat.d /etc/texmf/language.def.d /etc/texmf/updmap.d /etc/texmf/web2c /etc/udev/rules.d" CXXFLAGS="-O2 -march=prescott -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="assume-digests ccache distlocks fixpackages parallel-fetch preserve-libs protect-owned sandbox sfperms strict unmerge-logs unmerge-orphans userfetch" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/linux/distributions/gentoo" LC_ALL="cs_CZ.UTF-8" LDFLAGS="-Wl,-O1" LINGUAS="cs en" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_EXTRA_OPTS="--timeout=300" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage" USE="X a52 aac acl acpi alsa bash-completion branding bzip2 cairo cdparanoia cdr cjk cli cpudetection cracklib crypt cups curl dbus dri dts dvd dvdr dvdread emboss encode evo fam fbcon ffmpeg flac gdbm gif gnutls gpm gstreamer gtk hal iconv ieee1394 isdnlog java javascript jpeg jpeg2k kde laptop libnotify lm_sensors logrotate mad mikmod mmx mmxext mp3 mp4 mpeg mudflap ncurses nls nptl nptlonly nsplugin ogg opengl openmp pam pcmcia pcre pdf perl png ppds pppd python qt3 qt3support qt4 quicktime readline reflection rtc sdl session spell spl sse sse2 ssl startup-notification svg svga sysfs tcpd tga theora thunar tiff truetype unicode usb vcd vorbis wifi win32codecs x264 x86 xml xorg xscreensaver xulrunner xv xvid zlib" ALSA_CARDS="hda-intel" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" ELIBC="glibc" INPUT_DEVICES="evdev keyboard mouse synaptics" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="cs en" SANE_BACKENDS="net" USERLAND="GNU" VIDEO_CARDS="radeon" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, FFLAGS, INSTALL_MASK, LANG, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTDIR_OVERLAY
I'm affected by this bug too. Both emerge --depclean, and emerge @preserved-rebuild can't complete with an AMD64. Python was using up to 1.6G of virtual and 400M of Resident. At peak resident Python was allocated 800M of resident which is way to much. I don't want to spend the time to individually emerge each of the packages in the @preserved-rebuild set. Another system which is x86 can't complete either because of memory constraints.
Is there a way to turn off the @preserved-rebuild check at the end of every emerge? While that won't solve the problem, at the very least I'll be able to emerge simple things without having to watch the console and ^C before the memory-hogging checks take over.

I guess we can add a --quiet-preserve-libs option to prevent it from looking up the owners of the files. I already does this with --quiet.

Same problem here. A simple: emerge -1 gentoo-sources would eat up all memory on a 512MB machine that has no swap. This occurs while installing from the sandbox image into the live filesystem. The author of emerge apparently assumed infinite memory :-)
(In reply to comment #9) > Same problem here. A simple: > emerge -1 gentoo-sources If gentoo-sources triggers it, then that sounds more like bug 346749 than this bug which refers to @preserved-rebuild (a completely different operation).
This should be fixed since 2.2_rc68 by the following change: http://git.overlays.gentoo.org/gitweb/?p=proj/portage.git;a=commit;h=c4fdf0e53398e4917c64901da626ced4c6357010
