using a disk with captive-ntfs (i was using the binaries the program offers to download from microsoft) for a prolonged period (using a disk constantly for about an hour or so) causes the lufis process to allocate all my ram and swap (512mb of each) bringing my system to its knees. Reproducible: Always Steps to Reproduce: 1. use captive-ntfs and start copying or writing a large amount of files to/from an ntfs drive 2. this also happened when i tried to download the fedora core 2 dvd image to an ntfs hard drive 3. # emerge info Portage 2.0.51.19 (default-linux/x86/2005.0, gcc-3.4.3-20050110, glibc-2.3.4.20050125-r1, 2.6.11-gentoo-r4 i686) ================================================================= System uname: 2.6.11-gentoo-r4 i686 AMD Athlon(tm) XP 2600+ Gentoo Base System version 1.6.10 Python: dev-lang/python-2.3.5 [2.3.5 (#1, Mar 21 2005, 04:22:06)] dev-lang/python: 2.3.5 sys-devel/autoconf: 2.59-r6, 2.13 sys-devel/automake: 1.7.9-r1, 1.8.5-r3, 1.5, 1.4_p6, 1.6.3, 1.9.5 sys-devel/binutils: 2.15.92.0.2-r7 sys-devel/libtool: 1.5.14 virtual/os-headers: 2.6.8.1-r4 ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CFLAGS="-O2 -march=athlon-xp -pipe -fomit-frame-pointer" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.4/env /usr/kde/3.4/share/config /usr/kde/3.4/shutdown /usr/kde/3/share/config /usr/lib/X11/xkb /usr/share/config /usr/share/texmf/dvipdfm/config/ /usr/share/texmf/dvips/config/ /usr/share/texmf/tex/generic/config/ /usr/share/texmf/tex/platex/config/ /usr/share/texmf/xdvi/ /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O2 -march=athlon-xp -pipe -fomit-frame-pointer" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs autoconfig ccache distlocks sandbox sfperms" GENTOO_MIRRORS="http://www.mirrorservice.org/sites/www.ibiblio.org/gentoo/" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://bandit.cmt.wan/gentoo-portage" USE="x86 3dnow 3dnowext X aac alsa apache2 apm arts avi berkdb bitmap-fonts cdr crypt cups curl dvdr emacs emboss encode esd fam ffmpeg flac font-server foomaticdb fortran gdbm gif gnome gpm gtk gtk2 hal imagemagick imlib innodb ipv6 java jpeg junit kde kdeenablefinal kdexdltas libg++ libwww mad matroska mcal mikmod mmx motif mp3 mpeg mpm-prefork mysql nas ncurses nls nptl nptlonly offensive oggvorbis opengl oss pam pdflib perl php png python qt quicktime readline ruby sdl silc spell sse sse2 ssl subversion svg svga tcltk tcpd tetex tidy tiff truetype truetype-fonts type1-fonts v4l vhosts xml xml2 xmms xosd xslt xv xvid zlib" Unset: ASFLAGS, CBUILD, CTARGET, LANG, LC_ALL, LDFLAGS
I have the same effect using captive-ntfs to play mp3s with amarok from a ntfs partition. top shows that lufis is the process using the memory. Even after I umount the memory still doesn't get freed. 4203 root 20 0 429m 215m 820 D 0.3 42.9 2:25.06 lufis
see http://article.gmane.org/gmane.comp.file-systems.fuse.devel/1408 for the comment from the fuse developer. does the memory get freed after rmmod fuse? is the lufis process removed after umount? usually avery memory leak is freed after the program exited.
After umount and modprobe -r fuse memory usage is still very high. The lufis process still keeps on running. I bought 512MB more memory and can say that the memory usage doesn't continue to grow after some point and captive can be used if you have 1 GB of memory.
This bug tells me that captive is not for general usage .. Seems to be more for quick-copy-file or rescue cases. I had also big memory consumption with lufis+captive, but the memory was freed after I unmounted it. This is not really a gentoo bug, so please contact upstream so that they can improve their package. The captive project looks for a new maintainer, so in case you want to fix it yourself, you are invited to do so.
