I was told that emacs was out of memory, even though I still have over 1.5 gigabytes of RAM available. Emacs began consuming 100% CPU while at the same time was not doing any I/O (such as writing a corefile). Further investigation yields that there was some kind of bug or loop in the garbage collection process. What follows are my efforts to track down information on the bug. I've since learned further details about debugging as suggested by M-x report-bug. Next time this occurs I will be able to provide more information. The version of emacs used is emacs23_23.1+1-4~bpo50+1 within Debian lenny-backports: http://packages.debian.org/lenny-backports/emacs23 Please reference http://filebin.ca/ytkeqq/Emacs-23-GarbageCollectionBug.txt for the debugging information, including the very long stack trace. This should help with the line numbers provided in the backtrace. I hope this report will be helpful. :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: > In GNU Emacs 23.1.1 (i486-pc-linux-gnu) of 2009-12-28 on > localhost, modified by Debian configured using `configure > '--build=i486-linux-gnu' '--host=i486-linux-gnu' '--prefix=/usr' > '--sharedstatedir=/var/lib' '--libexecdir=/usr/lib' > '--localstatedir=/var/lib' '--infodir=/usr/share/info' > '--mandir=/usr/share/man' '--with-pop=no' '--without-gpm' > '--without-dbus' > '--enable-locallisppath=/etc/emacs23:/etc/emacs:/usr/local/share/emacs/23.1/site-lisp:/usr/local/share/emacs/site-lisp:/usr/share/emacs/23.1/site-lisp:/usr/share/emacs/site-lisp:/usr/share/emacs/23.1/leim' > '--with-x=no' 'build_alias=i486-linux-gnu' > 'host_alias=i486-linux-gnu' 'CFLAGS=-DDEBIAN -g3 -Os '' > Important settings: value of $LC_ALL: nil value of $LC_COLLATE: > nil value of $LC_CTYPE: nil value of $LC_MESSAGES: nil value of > $LC_MONETARY: nil value of $LC_NUMERIC: nil value of $LC_TIME: nil > value of $LANG: nil value of $XMODIFIERS: nil > locale-coding-system: nil default-enable-multibyte-characters: t > Major mode: Lisp Interaction > Minor modes in effect: savehist-mode: t recentf-mode: t > display-time-mode: t desktop-save-mode: t shell-dirtrack-mode: t > menu-bar-mode: t file-name-shadow-mode: t global-font-lock-mode: t > font-lock-mode: t global-auto-composition-mode: t > auto-composition-mode: t auto-encryption-mode: t > auto-compression-mode: t size-indication-mode: t > column-number-mode: t line-number-mode: t transient-mark-mode: t --=-=-= Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- iD8DBQFLS2BNqD8+Qs0aSBsRApqBAJsEwHQOqf8SjKllIU/w9x+0PoNmNACfU3yP 3bN4EQ3gQO64g7hpZgx2a0E= =wFRO -----END PGP SIGNATURE----- --=-=-=--
