It could help to locate the issue (for obvious ones). But at the end we may need something to reproduce it. ------------------------------------------------------------------------ [2013-01-09 08:52:53] hufeng1987 at gmail dot com i hope i could locate which code occurred these leak. but i failed because it run's too much more code. million lines of code running. any suggestion help me find out the bad code? i tried my hard to find it out ,but still got nothing. -------------------------------------------------------------------------------- ------------------------------------------------------ [09-Jan-2013 16:49:52.459798] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "/root/soft/phpall/php- 5.4.10/Zend/zend_hash.c(339) : Actual location (location was relayed)" [09-Jan-2013 16:49:52.459810] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "Last leak repeated 849 times" [09-Jan-2013 16:49:52.459822] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "[Wed Jan 9 16:49:52 2013] Script: '-'" [09-Jan-2013 16:49:52.459835] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "/root/soft/phpall/cache/APC- 3.1.13/apc_compile.c(219) : Freeing 0x100EF5C0 (32 bytes), script=-" [09-Jan-2013 16:49:52.459848] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "Last leak repeated 53 times" [09-Jan-2013 16:49:52.459860] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "[Wed Jan 9 16:49:52 2013] Script: '-'" [09-Jan-2013 16:49:52.459872] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "/root/soft/phpall/php- 5.4.10/Zend/zend_compile.c(114) : Freeing 0x100F0648 (54 bytes), script=-" [09-Jan-2013 16:49:52.459885] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "Last leak repeated 182 times" [09-Jan-2013 16:49:52.459897] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "[Wed Jan 9 16:49:52 2013] Script: '-'" [09-Jan-2013 16:49:52.459909] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "/root/soft/phpall/php- 5.4.10/Zend/zend_compile.c(2867) : Freeing 0x100F17C8 (240 bytes), script=-" [09-Jan-2013 16:49:52.459924] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "/root/soft/phpall/php- 5.4.10/Zend/zend_hash.c(236) : Actual location (location was relayed)" [09-Jan-2013 16:49:52.459935] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "Last leak repeated 9 times" [09-Jan-2013 16:49:52.459947] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "[Wed Jan 9 16:49:52 2013] Script: '-'" [09-Jan-2013 16:49:52.459958] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "/root/soft/phpall/php- 5.4.10/Zend/zend_hash.c(450) : Freeing 0x100F29B0 (128 bytes), script=-" [09-Jan-2013 16:49:52.459969] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "Last leak repeated 29 times" [09-Jan-2013 16:49:52.459980] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "[Wed Jan 9 16:49:52 2013] Script: '-'" [09-Jan-2013 16:49:52.459991] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "/root/soft/phpall/php- 5.4.10/Zend/zend_vm_execute.h(380) : Freeing 0x100F4198 (56 bytes), script=-" [09-Jan-2013 16:49:52.460002] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "/root/soft/phpall/php- 5.4.10/Zend/zend_alloc.c(2529) : Actual location (location was relayed)" [09-Jan-2013 16:49:52.460013] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "Last leak repeated 471 times" [09-Jan-2013 16:49:52.460024] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "[Wed Jan 9 16:49:52 2013] Script: '-'" [09-Jan-2013 16:49:52.460035] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "/root/soft/phpall/php- 5.4.10/Zend/zend_compile.c(3309) : Freeing 0x10493948 (64 bytes), script=-" [09-Jan-2013 16:49:52.460056] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "/root/soft/phpall/php- 5.4.10/Zend/zend_hash.c(339) : Actual location (location was relayed)" [09-Jan-2013 16:49:52.460069] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "Last leak repeated 21 times" [09-Jan-2013 16:49:52.460080] WARNING: pid 2813, fpm_stdio_child_said(), line 166: [pool www] child 2815 said into stderr: "=== Total 7991 memory leaks detected ===" [09-Jan-2013 16:49:52.460091] DEBUG: pid 2813, fpm_event_loop(), line 411: event module triggered 1 events ------------------------------------------------------------------------ [2013-01-09 08:45:30] paj...@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report.
