Edit report at http://bugs.php.net/bug.php?id=49308&edit=1 ID: 49308 Updated by: [email protected] Reported by: f4ckm5 at web dot de Summary: random crashes on freeing mysqli result storage -Status: Assigned +Status: Feedback Type: Bug Package: MySQLi related Operating System: Windows Server 2003 SP2 32Bit PHP Version: 5.3, 6 (2009-08-22) Assigned To: mysql New Comment: Checking if this thing is still alive. Do you get the same problem with 5.3.2? Thanks! Previous Comments: ------------------------------------------------------------------------ [2009-09-18 08:37:44] [email protected] Well, do you have any tips in what to do with the trace? Sorry, but a reproducible case would be much more worth than the trace. Alternatively, is it possible to enable the mysqlnd trace? ------------------------------------------------------------------------ [2009-08-29 15:31:34] f4ckm5 at web dot de Do you have any tips on how to find the respective lines of code in a 70000 lines of code project which eventually cause the crash? All i can see is the dying apache worker thread and the corresponding message in the system log. And it is very annoying, that this happens only on the productive system. No crashes on our development and test machines. I would gladly provide a test script. Just tell me where to start digging. ------------------------------------------------------------------------ [2009-08-26 15:38:34] [email protected] Any chance to provide a test script? I know its hard, but its also hard to say anything based on the backtrace and without a reproducible test case. Thanks, Ulf ------------------------------------------------------------------------ [2009-08-21 09:31:38] f4ckm5 at web dot de I used the latest Snapshot 5.3.1-dev from Thu Aug 20 15:19:10 2009 The crashes became less frequent. Instead of 10 in 5 Minutes i caught only 5 in 3.5 hours. But the crashes still occur: ############################################################# Thread 250 - System ID 9828 Entry point msvcrt!_endthreadex+2f Create time 21.08.2009 09:11:23 Time spent in user mode 0 Days 0:0:0.171 Time spent in kernel mode 0 Days 0:0:0.78 Function Arg 1 Arg 2 Arg 3 Source php5ts!_zend_mm_free_int+139 056cf838 00050004 00720336 php5ts!_efree+36 012296e8 06894910 00725877 php5ts!_zval_ptr_dtor+66 068948e4 006ad310 06868980 php5ts!zend_hash_destroy+27 06876538 06868980 015a1665 php5ts!zend_object_std_dtor+2b 06868980 056ce490 06868980 php_mysqli!mysqli_objects_free_storage+25 06868980 056ce490 05a733e4 php_mysqli!mysqli_result_free_storage+28 06868980 056ce490 056ce490 php5ts!zend_objects_store_del_ref_by_handle_ex+1b6 0000002b 015b1600 056ce490 php5ts!zend_objects_store_del_ref+1e 06868960 056ce490 00000000 php5ts!_zval_dtor_func+76 06868960 00000000 05ab9050 php5ts!ZEND_ASSIGN_SPEC_CV_VAR_HANDLER+237 0546fbfc 056ce490 0546fe78 php5ts!execute+29e 05ab9050 056ce400 00000000 php5ts!zend_execute_scripts+f6 00000008 056ce490 00000000 php5ts!php_execute_script+22d 0546fe78 056ce490 00000003 php5apache2_2!php_handler+5d0 012c18b8 00615988 012c18b8 libhttpd!ap_run_handler+21 012c18b8 012c18b8 012c18b8 libhttpd!ap_invoke_handler+ae 00000000 012bc860 0546ff3c libhttpd!ap_die+29e 012c18b8 00000000 0065fb90 libhttpd!ap_get_request_note+1ccc 012bc860 012bc860 012bc860 libhttpd!ap_run_process_connection+21 012bc860 0062b108 0546ff84 libhttpd!ap_process_connection+33 012bc860 012b1820 00000000 libhttpd!ap_regkey_value_remove+c7c 012bc858 00000000 00000000 msvcrt!_endthreadex+a3 012a7d08 00000000 00000000 kernel32!BaseThreadStart+34 77b9b4bc 012a7d08 00000000 PHP5TS!_ZEND_MM_FREE_INT+139In httpd__PID__7192__Date__08_21_2009__Time_09_11_24AM__898__First chance exception 0XC0000005.dmp the assembly instruction at php5ts!_zend_mm_free_int+139 in C:\PHP\php5ts.dll from The PHP Group has caused an access violation exception (0xC0000005) when trying to read from memory location 0x02080174 on thread 250 Module Information Image Name: C:\PHP\php5ts.dll Symbol Type: PDB Base address: 0x006a0000 Time Stamp: Thu Aug 20 15:19:10 2009 Checksum: 0x00000000 Comments: COM DLL: False Company Name: The PHP Group ISAPIExtension: False File Description: PHP Script Interpreter ISAPIFilter: False File Version: 5.3.1-dev Managed DLL: False Internal Name: PHP Script Interpreter VB DLL: False Legal Copyright: Copyright © 1997-2009 The PHP Group Loaded Image Name: php5ts.dll Legal Trademarks: PHP Mapped Image Name: C:\PHP\php5ts.dll Original filename: php5ts.dll Module name: php5ts Private Build: Single Threaded: False Product Name: PHP Module Size: 5,45 MBytes Product Version: 5.3.1-dev Symbol File Name: C:\Dokumente und Einstellungen\Administrator.HML\Desktop\php-debug-pack-5.3-win32-VC6-x86-latest\php5ts.pdb Special Build: & ------------------------------------------------------------------------ [2009-08-20 09:53:08] [email protected] Please try using this snapshot: http://snaps.php.net/php5.3-latest.tar.gz For Windows: http://windows.php.net/snapshots/ ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
