From: php at grooky dot com Operating system: RedHat 9 PHP version: 4.3.3RC1 PHP Bug Type: Reproducible crash Bug description: Apache 2 Segfault when receiving a signal
Description: ------------ Apache 2 root process core when it received a signal (for example HUP or USR1 at logrotation) when php module loaded. Bug is reproductible at least with Apache 2.0.44 .45 .46 or .47 and with php 4.3.1, 4.3.2, 4.3.3RC1, CVS-STABLE. Bug is reproductible with linux 2.4.20 or 2.4.21 but NOT with the standard RedHat 9 kernel. To reproduce the segfault : kill -HUP "pid of apache root process" apachectl graceful Error log show : "[notice] seg fault or similar nasty error detected in the parent process" Reproduce code: --------------- php configure : ./configure --enable-debug --with-mysql --with-ldap --with-gettext --enable-force-cgi-redirect --with-apxs2=/tmp/apache2/bin/apxs --enable-track-vars --with-config-file-path=/etc standard php.ini As apache core only with any custom kernel I tried (but not with redHat one), here is my kernel configuration : My kernel configuration : http://www.grooky.com/linux.config I found few people on newgroup's archive with exaclty the same segfault. None got solution. Expected result: ---------------- Expected result : apache should reload it's configration Actual result: -------------- (gdb) bt #0 0x26a5cc20 in sapi_initialize_empty_request (tsrm_ls=0x8b776452) at /usr/src/php-4.3.3RC1/main/SAPI.c:424 #1 0x26a57210 in php_module_startup (sf=0x26ad5e20, additional_modules=0x26ad6100, num_additional_modules=1) at /usr/src/php-4.3.3RC1/main/main.c:1094 #2 0x26a93fdb in php_apache2_startup (sapi_module=0x26ad5e20) at /usr/src/php-4.3.3RC1/sapi/apache2handler/sapi_apache2.c:297 #3 0x26a9410b in php_apache_server_startup (pconf=0x80da508, plog=0x81165f8, ptemp=0x811d810, s=0x26ad5e20) at /usr/src/php-4.3.3RC1/sapi/apache2handler/sapi_apache2.c:396 #4 0x08094240 in ap_run_post_config (pconf=0x80da508, plog=0x81165f8, ptemp=0x811d810, s=0x80de450) at config.c:131 #5 0x080986e2 in main (argc=3, argv=0x5db89cd4) at main.c:649 #6 0x267dba07 in __libc_start_main () from /lib/i686/libc.so.6 -- Edit bug report at http://bugs.php.net/?id=24567&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=24567&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=24567&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=24567&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=24567&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=24567&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=24567&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=24567&r=support Expected behavior: http://bugs.php.net/fix.php?id=24567&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=24567&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=24567&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=24567&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=24567&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=24567&r=dst IIS Stability: http://bugs.php.net/fix.php?id=24567&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=24567&r=gnused
