Could you try 4.1.0 and report the result? Previous Comments: ------------------------------------------------------------------------ [2001-04-29 11:32:19] [EMAIL PROTECTED] reclassify ------------------------------------------------------------------------ [2001-02-23 16:06:24] [EMAIL PROTECTED] It seems that after a while of server inactivity, the apache processes go into a mode where they continue to just use cpu - the processes become unseable for processing http requests since they just stay in this state. A server restart is needed to correct the problem. A process stack listing shows the process to be within the PHP module at the time: 0x400c2248: chunk_free + 0x270 (404407f4, 8118740, 4042f0f3) 0x400c1fba: __cfree + 0xaa (8118740, 404407f4, 4043da80, 4042f0f3, 624407f4, 6e9f190) + 34 0x4037ebb0: zend_hash_del_key_or_index + 0x1d8 (8111048, 4042f0ea, 9, 8da99e0, 0, 404407f4) + 10 0x4037c0af: zend_unregister_functions + 0x67 (4043da14, ffffffff, 0, 404407f4, 81329f8) 0x4037c1bb: module_destructor + 0x73 (8132a28, 404407f4, 4000ae60, bffffdc4) 0x4037ec24: zend_hash_destroy + 0x30 (40455760, 404407f4) 0x4037b2f5: zend_shutdown + 0x25 (404407f4) 0x4038a4de: php_module_shutdown + 0x32 (404407f4) 0x4038a4a5: php_module_shutdown_wrapper + 0x15 (40437840, 403887f8) 0x40388817: php_child_exit_handler + 0x1f (80d15b0, 8151c70, 18, 40437940) 0x0806fa61: ap_child_exit_modules + 0x49 (8151c70, 80d15b0) 0x080758d5: clean_child_exit + 0x1d (0) 0x08077587: just_die + 0x1f (a) 0x080775a9: usr1_handler + 0x15 (a, 0, 0, 2b, 2b, bffffdc4) + dc 0x40086c68: sigaction + 0x268 (8126e70, 81479d8, 814dfa8, 6c060002, 2000a0a, c65451e8) + 18 0x080788b7: child_main + 0x1b7 (b, b, 0) 0x08078ebc: make_child + 0x118 (80d15b0, b, 3a8ad8e0, 401581ec, 4053e480, 0) + a0 0x08079236: perform_idle_server_maintenance + 0x2b2 (401581ec, ffffffff, 0, d, 0) 0x08079765: standalone_main + 0x355 (2, bffffdc4, bffffdc4, 40013ed0, 8049c54, 80cc6a4) + 30 0x08079d33: main + 0x357 (2, bffffdc4, bffffdd0, 40013868, 2, 8050600) 0x400809cb: __libc_start_main + 0xff (80799dc, 2, bffffdc4, 804fc60, 80b127c, 4000ae60) + 40000248 PHP configuration options listed below: ./configure --prefix=/usr --with-apxs=/usr/sbin/httpd/bin/apxs --with-config-file-path=/etc/httpd --enable-safe-mode --with-exec-dir=/usr/sbin --with-system-regex --disable-debug --with-zlib --with-dbdm --with-db2 --enable-debugger --enable-magic-quotes --enable-track-vars --enable-sysvsem --enable-sysvshm --enable-track-vars --with-xml --with-ftp --with-pgsql --with-cybercash=/usr/src/cybercash/mck-3.3.0-i586-pc-linux-gnulibc2.1 glibc version is 2.1.3 php module was compiled with egcs-2.91.66 apache version is 1.3.14 kernel version 2.2.14 We also experienced this problem with PHP version 4.0.2. After upgrading to the latest PHP, is seems that the problem is occuring less frequently. ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=9431&edit=1 -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
