--- Begin Message ---Package: php5-xcache Version: 2.0.0-1 Severity: important When XCache's regular cache is enabled (xcache.size isn't 0), after loading a couple of large of PHP scripts, XCache seems to crash. Basically I see things like this in my Apache error log: [Tue Jul 24 15:37:32 2012] [notice] child pid 19048 exit signal Segmentation fault (11) [Tue Jul 24 15:37:32 2012] [notice] child pid 19050 exit signal Segmentation fault (11) [Tue Jul 24 15:37:34 2012] [notice] child pid 19052 exit signal Segmentation fault (11) [Tue Jul 24 15:37:36 2012] [notice] child pid 19053 exit signal Segmentation fault (11) And the pages never load in the browser. If I turn off XCache's regular cacher (but still leave XCache's variable cacher on), then things seem normal. I can load many many large PHP scripts and my server doesn't seem to ever crash. I peformed many tests with XCacher's regular cache on and off, to narrow down that this indeed was the problem in my server crashing. I noticed the larger I make xcache.size, the longer it takes for XCache to start crashing. -- System Information: Debian Release: wheezy/sid APT prefers unstable APT policy: (700, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 3.0.0-2-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages php5-xcache depends on: ii libapache2-mod-php5 [phpapi-2 5.4.4-3 server-side, HTML-embedded scripti ii libc6 2.13-35 Embedded GNU C Library: Shared lib ii php5-cgi [phpapi-20100525] 5.4.4-3 server-side, HTML-embedded scripti ii php5-cli [phpapi-20100525] 5.4.4-3 command-line interpreter for the p php5-xcache recommends no packages. php5-xcache suggests no packages. -- Configuration Files: /etc/php5/mods-available/xcache.ini changed: ; configuration for php Xcache module [xcache-common] ;; install as zend extension (recommended), normally "$extension_dir/xcache.so" zend_extension = /usr/lib/php5/20100525/xcache.so [xcache.admin] xcache.admin.enable_auth = On ; Configure this to use admin pages ; xcache.admin.user = "mOo" ; xcache.admin.pass = md5($your_password) ; xcache.admin.pass = "" [xcache] ; ini only settings, all the values here is default unless explained ; select low level shm/allocator scheme implemenation xcache.shm_scheme = "mmap" ; to disable: xcache.size=0 ; to enable : xcache.size=64M etc (any size > 0) and your system mmap allows xcache.size = 16M ; set to cpu count (cat /proc/cpuinfo |grep -c processor) xcache.count = 2 ; just a hash hints, you can always store count(items) > slots xcache.slots = 8K ; ttl of the cache item, 0=forever xcache.ttl = 0 ; interval of gc scanning expired items, 0=no scan, other values is in seconds xcache.gc_interval = 0 ; same as aboves but for variable cache xcache.var_size = 16M xcache.var_count = 1 xcache.var_slots = 8K ; default ttl xcache.var_ttl = 0 xcache.var_maxttl = 0 xcache.var_gc_interval = 300 xcache.test = Off ; N/A for /dev/zero xcache.readonly_protection = Off ; for *nix, xcache.mmap_path is a file path, not directory. ; Use something like "/tmp/xcache" if you want to turn on ReadonlyProtection ; 2 group of php won't share the same /tmp/xcache ; for win32, xcache.mmap_path=anonymous map name, not file path xcache.mmap_path = "/dev/zero" ; leave it blank(disabled) or "/tmp/phpcore/" ; make sure it's writable by php (without checking open_basedir) xcache.coredump_directory = "" ; per request settings xcache.cacher = On xcache.stat = On xcache.optimizer = Off [xcache.coverager] ; per request settings ; enable coverage data collecting for xcache.coveragedump_directory and xcache_coverager_start/stop/get/clean() functions (will hurt executing performance) xcache.coverager = Off ; ini only settings ; make sure it's readable (care open_basedir) by coverage viewer script ; requires xcache.coverager=On xcache.coveragedump_directory = "" -- no debconf information
