When dovecot 1.1.7-r1 is compiled with the -O3 flag, imap daemons are locked in memory for ever. After a TLS connection has been establish and some transactions have been done, imap processes will continue to spin in memory after you have left thunderbird. Imap processes cannot be stopped/killed. If dovecot is compiled with the -O2 flag, the issue isn't reproductible. Also, neither ctrace nor gdb have returned anything. It is also similar to what happened with bug 246421 about enigmail. Reproducible: Always Steps to Reproduce: 1. CFLAGS="-march=k8 -O3 -pipe" USE="berkdb managesieve mysql pam sieve ssl" emerge net-mail/dovecot-1.1.7-r1 2. thunderbird 3. read mails and quit thunderbird 4. ps aux | grep imap Actual Results: Cannot end imap process Expected Results: Only imap-login should stay in memory dev-libs/openssl-0.9.8i USE="gmp (sse2) zlib -bindist -kerberos -test" # emerge --info Portage 2.2_rc17 (default/linux/amd64/2008.0, gcc-4.3.2, glibc-2.9_p20081201-r0, 2.6.28-rc8-vesa x86_64) ================================================================= System uname: Linux-2.6.28-rc8-vesa-x86_64-AMD_Athlon-tm-_64_Processor_3200+-with-glibc2.2.5 Timestamp of tree: Mon, 15 Dec 2008 08:45:01 +0000 ccache version 2.4 [enabled] app-shells/bash: 3.2_p33 dev-java/java-config: 1.3.7-r1, 2.1.6-r1 dev-lang/python: 2.5.2-r8 dev-python/pycrypto: 2.0.1-r6 dev-util/ccache: 2.4-r8 dev-util/cmake: 2.6.2 sys-apps/baselayout: 1.12.12 sys-apps/sandbox: 1.2.18.1-r3 sys-devel/autoconf: 2.13, 2.63 sys-devel/automake: 1.5, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10.2 sys-devel/binutils: 2.19 sys-devel/gcc-config: 1.4.0-r4 sys-devel/libtool: 2.2.6a virtual/os-headers: 2.6.27-r2 ACCEPT_KEYWORDS="amd64" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=k8 -O3 -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /etc/splash/livecd-2007.0/1280x1024.cfg /lib/rcscripts/addons /sbin/rc /sbin/splash-functions-bl1.sh /sbin/splash-functions.sh /usr/local/share/cursors/xorg-x11/default/index.theme /usr/share/hddtemp/hddtemp.db /usr/src/linux/.config /var/bind" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/php/apache2-php5/ext-active/ /etc/php/cgi-php5/ext-active/ /etc/php/cli-php5/ext-active/ /etc/revdep-rebuild /etc/splash /etc/terminfo /etc/texmf/language.dat.d /etc/texmf/language.def.d /etc/texmf/updmap.d /etc/texmf/web2c /etc/udev/rules.d" CXXFLAGS="-march=k8 -O3 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="ccache collision-protect distlocks fixpackages parallel-fetch preserve-libs protect-owned sandbox sfperms splitdebug strict unmerge-orphans userfetch userpriv" GENTOO_MIRRORS="ftp://ftp.free.fr/mirrors/ftp.gentoo.org/ http://linux.rz.ruhr-uni-bochum.de/download/gentoo-mirror/ http://mirrors.sec.informatik.tu-darmstadt.de/gentoo/" LANG="fr_FR.UTF-8" LC_ALL="fr_FR.UTF-8" LDFLAGS="-Wl,-O1 -Wl,--as-needed" LINGUAS="fr" MAKEOPTS="-j2"

Same problem here, except my CFLAGS="-march=prescott -O2 -pipe -fomit-frame-pointer", and dovecot was build with USE="ipv6 pam ssl".
Probably the kernel bug reported below: http://www.dovecot.org/list/dovecot/2008-December/035707.html http://lkml.indiana.edu/hypermail/linux/kernel/0812.1/00998.html http://lkml.org/lkml/2008/12/14/162

Oh, well... Jimmy.Jazz@gmx.net: is your problem also solved with a different kernel version?
Reopen if it still happens with current versions.
