I unmasked and installed apc and it seemed to work well for a while. Hours later, I see that Apache is segfaulting all over the place and won't serve any pages. Looking at my apache error_log, I see these entries about an hour and a half after I installed apc and restarted apache: [Sun Jun 18 21:44:44 2006] [apc-error] apc_sma_free: could not locate address 0x555556340ac0 [Sun Jun 18 21:45:19 2006] [apc-error] apc_sma_free: could not locate address 0x55555616bc80 [Sun Jun 18 21:53:18 2006] [apc-error] apc_sma_free: could not locate address 0x55555632c4b0 Then some of these: [Sun Jun 18 21:09:47 2006] [apc-warning] GC cache entry '/home/user/public_html/global.php' (dev=771 ino=12286 37) was on gc-list for 3621 seconds [Sun Jun 18 21:09:47 2006] [apc-warning] GC cache entry '/home/user/public_html/includes/config.php' (dev=771 ino=602598) was on gc-list for 3621 seconds Then finally nothing but these: [Sun Jun 18 22:11:41 2006] [notice] child pid 2039 exit signal Segmentation fault (11) [Sun Jun 18 22:11:42 2006] [notice] child pid 2442 exit signal Segmentation fault (11) [Sun Jun 18 22:11:44 2006] [notice] child pid 563 exit signal Segmentation fault (11) [Sun Jun 18 22:11:44 2006] [notice] child pid 2443 exit signal Segmentation fault (11) [Sun Jun 18 22:11:41 2006] [notice] child pid 2039 exit signal Segmentation fault (11) [Sun Jun 18 22:11:42 2006] [notice] child pid 2442 exit signal Segmentation fault (11) [Sun Jun 18 22:11:44 2006] [notice] child pid 563 exit signal Segmentation fault (11) [Sun Jun 18 22:11:44 2006] [notice] child pid 2443 exit signal Segmentation fault (11) emerge --info: Portage 2.1.1_pre1 (default-linux/amd64/2005.0, gcc-hardened, glibc-2.3.5-r3, 2.6.16-gentoo-r9 x86_64) ================================================================= System uname: 2.6.16-gentoo-r9 x86_64 AMD Opteron(tm) Processor 246 Gentoo Base System version 1.6.14 ccache version 2.3 [disabled] dev-lang/python: 2.4.2 dev-python/pycrypto: 2.0.1-r5 dev-util/ccache: 2.3 dev-util/confcache: [Not Present] sys-apps/sandbox: 1.2.17 sys-devel/autoconf: 2.13, 2.59-r7 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r1 sys-devel/binutils: 2.16.1-r2 sys-devel/gcc-config: 1.3.13-r2 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="amd64" AUTOCLEAN="yes" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=k8 -O2 -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /var/bind" CONFIG_PROTECT_MASK="/etc/env.d /etc/gconf /etc/revdep-rebuild /etc/terminfo" CXXFLAGS="-march=k8 -O2 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks metadata-transfer sandbox sfperms strict userpriv usersandbox" GENTOO_MIRRORS="http://gentoo.osuosl.org http://www.ibiblio.org/pub/Linux/distributions/gentoo" MAKEOPTS="-j3" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude='/distfiles' --exclude='/local' --exclude='/packages'" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="amd64 apache2 avi berkdb cli crypt dri eds emboss encode foomaticdb fortran gd gif gstreamer hardened imap imlib isdnlog jpeg libwww lzw lzw-tiff maildir mysql ncurses nptl nptlonly pam-mysql pcre pdflib perl png pppd python quicktime readline reflection sdl session spell spl ssl tcpd tiff usb xml xorg zlib elibc_glibc kernel_linux userland_GNU" Unset: CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, LINGUAS, PORTAGE_RSYNC_EXTRA_OPTS, PORTDIR_OVERLAY
UPSTREAM CVS has about six months worth of bugfixing however no intentions to release a new version anytime soon ("There is always one more bug to fix."). I propose to make a revision bump to the apc-3.0.10 ebuild(s) that patches 3.0.10 up to the current CVS version. Thoughts?
APC 3.0.11, which contains about six months worth of bugfixes, is in the tree now. Please try with this new version and open a new issue if the problem persists. Thank you!
