true, but I can't reproduce it on my dev server... Previous Comments: ------------------------------------------------------------------------ [2007-08-23 11:46:12] [EMAIL PROTECTED] Nobody asked you to run it on live site.. ------------------------------------------------------------------------ [2007-08-23 11:33:40] jille at hexon dot cx I can't run 5.2.4-dev in gdb on a live server. That will slow down about 1000+ sites i`m hosting. But I will try to run one server without Zend extensions. Let`s see whether I still get crashes on that one ------------------------------------------------------------------------ [2007-08-23 10:26:12] [EMAIL PROTECTED] First get the latst 5.2.4-dev snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz Then compile it with using --enable-debug in your configure line. Before you launch Apache, disable all Zend extensions in your php.ini. Run Apache under GDB: # gdb --arg httpd -X (gdb) run Then do the things required to crash it and: <segfault> (gdb) bt And you should have better backtrace. Although it seems to be coming from the filter extension by looking at the current backtrace, it's easier to pinpoint the exact place when the debug symbols are around. ------------------------------------------------------------------------ [2007-08-23 10:03:39] jille at hexon dot cx Description: ------------ I have found these 2 lines in my syslog, this crash happens nearly a few times a day. Aug 23 10:37:00 hillsbrad crashdump[10305]: httpd crashed Aug 23 10:37:00 hillsbrad crashdump[10305]: crash report written to: /Library/Logs/CrashReporter/httpd.crash.log My website is being used by 400 users a day, on the 'crashing page' several images can be uploaded. Reproduce code: --------------- I tried to reproduce the crash, but it didn`t work out. I`ve added some debug code, some debuglines appear about 30 seconds before the crash. Some a few seconds after (they are not reported in the same way). It might also be that the debugging lines are not even reached. Expected result: ---------------- I don`t know what exactly happens to the user on the website. I`ve never got any complaints about it or something. It could be a delayed crash or something (eg: the uploads create some buffer overflow, and apache crashes on the next request or something.) But I would expect not to see a crash happen Actual result: -------------- Exception: EXC_BAD_ACCESS (0x0001) Codes: KERN_INVALID_ADDRESS (0x0001) at 0x310074f4 Thread 0 Crashed: 0 libphp5.so 0x022f2010 _zend_mm_free_int + 544 1 libphp5.so 0x02323808 zend_hash_destroy + 168 2 libphp5.so 0x023161b4 _zval_dtor_func + 164 3 libphp5.so 0x02304100 _zval_ptr_dtor + 80 4 libphp5.so 0x0207f4ec zm_deactivate_filter + 140 5 libphp5.so 0x0231a95c module_registry_cleanup + 44 6 libphp5.so 0x02323ce8 zend_hash_apply + 152 7 libphp5.so 0x02316c1c zend_deactivate_modules + 92 8 libphp5.so 0x022c1298 php_request_shutdown + 328 9 libphp5.so 0x023ca1cc apache_php_module_main + 236 10 libphp5.so 0x023cb8bc send_php + 1212 11 libphp5.so 0x023cb968 send_parsed_php + 56 12 httpd 0x0000dd18 ap_invoke_handler + 232 13 httpd 0x00017dd4 process_request_internal + 640 14 httpd 0x00017e54 ap_process_request + 72 15 httpd 0x00006b60 child_main + 1832 16 httpd 0x00006dc4 make_child + 312 17 httpd 0x00007660 standalone_main + 852 18 httpd 0x00007d74 main + 1052 19 httpd 0x0000238c _start + 348 20 httpd 0x0000222c start + 60 Thread 0 crashed with PPC Thread State 64: srr0: 0x00000000022f2010 srr1: 0x100000000200f030 vrsave: 0x0000000000000000 cr: 0x48000448 xer: 0x0000000000000000 lr: 0x00000000022f1e90 ctr: 0x0000000000003ddc r0: 0x0000000000000000 r1: 0x00000000bfffe220 r2: 0x0000000000000001 r3: 0x000000000185e800 r4: 0x00000000002c74b0 r5: 0x0000000000000002 r6: 0x00000000002c74a8 r7: 0x0000000000000000 r8: 0x0000000000000010 r9: 0x00000000002c74e8 r10: 0x00000000002c74e8 r11: 0x00000000310074e8 r12: 0x0000000000003ddc r13: 0x0000000000000000 r14: 0x0000000000000000 r15: 0x0000000000000000 r16: 0x0000000000000000 r17: 0x0000000000000000 r18: 0x0000000000000000 r19: 0x0000000000000000 r20: 0x0000000000000000 r21: 0x0000000000000000 r22: 0x0000000000057314 r23: 0x0000000000057314 r24: 0x0000000000057314 r25: 0x0000000000057314 r26: 0x000000000187a638 r27: 0x000000000231a930 r28: 0x000000000185e800 r29: 0x0000000000000040 r30: 0x00000000002c74a8 r31: 0x00000000022f1e04 Binary Images Description: 0x1000 - 0x4ffff httpd /usr/sbin/httpd 0x65000 - 0x67fff mod_log_config.so /usr/libexec/httpd/mod_log_config.so 0x6a000 - 0x6bfff mod_mime.so /usr/libexec/httpd/mod_mime.so 0x6e000 - 0x70fff mod_status.so /usr/libexec/httpd/mod_status.so 0x73000 - 0x75fff mod_info.so /usr/libexec/httpd/mod_info.so 0x78000 - 0x81fff mod_rewrite.so /usr/libexec/httpd/mod_rewrite.so 0x85000 - 0x86fff mod_access.so /usr/libexec/httpd/mod_access.so 0x89000 - 0x8afff mod_auth_apple.so /usr/libexec/httpd/mod_auth_apple.so 0x8d000 - 0x8dfff mod_setenvif.so /usr/libexec/httpd/mod_setenvif.so 0x90000 - 0x90fff mod_hfs_apple.so /usr/libexec/httpd/mod_hfs_apple.so 0x93000 - 0x95fff mod_digest_apple.so /usr/libexec/httpd/mod_digest_apple.so 0x98000 - 0xb4fff libssl.so /usr/libexec/httpd/libssl.so 0xd1000 - 0xeefff libjpeg.62.dylib /sw/lib/libjpeg.62.dylib 0xf6000 - 0xf7fff ZendExtensionManager.so /usr/local/Zend/lib/ZendExtensionManager.so 0x205000 - 0x223fff libpng.3.dylib /sw/lib/libpng.3.dylib 0x282000 - 0x286fff libmnogocharset-3.3.dylib /usr/local/mnogosearch/lib/libmnogocharset-3.3.dylib 0x405000 - 0x4fefff libiconv.2.dylib /sw/lib/libiconv.2.dylib 0x1008000 - 0x1048fff libfreetype.6.dylib /sw/lib/libfreetype.6.dylib 0x118f000 - 0x129ffff libxml2.2.dylib /sw/lib/libxml2.2.dylib 0x14d5000 - 0x1600fff ZendOptimizer.so /usr/local/Zend/lib/Optimizer-3.2.8/php-5.2.x/ZendOptimizer.so 0x2008000 - 0x2660fff libphp5.so /usr/libexec/httpd/libphp5.so 0x287d000 - 0x2947fff libmnogosearch-3.3.dylib /usr/local/mnogosearch/lib/libmnogosearch-3.3.dylib 0x8fe00000 - 0x8fe52fff dyld 46.12 /usr/lib/dyld 0x90000000 - 0x901bcfff libSystem.B.dylib /usr/lib/libSystem.B.dylib 0x90214000 - 0x90219fff libmathCommon.A.dylib /usr/lib/system/libmathCommon.A.dylib 0x907bb000 - 0x90894fff com.apple.CoreFoundation 6.4.7 (368.28) /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation 0x908df000 - 0x909e1fff libicucore.A.dylib /usr/lib/libicucore.A.dylib 0x90a3b000 - 0x90abffff libobjc.A.dylib /usr/lib/libobjc.A.dylib 0x90b6f000 - 0x90b81fff libauto.dylib /usr/lib/libauto.dylib 0x9110f000 - 0x9111dfff libz.1.dylib /usr/lib/libz.1.dylib 0x91120000 - 0x912dbfff com.apple.security 4.6 (29770) /System/Library/Frameworks/Security.framework/Versions/A/Security 0x91431000 - 0x9143cfff libgcc_s.1.dylib /usr/lib/libgcc_s.1.dylib 0x91a19000 - 0x91ae0fff libcrypto.0.9.7.dylib /usr/lib/libcrypto.0.9.7.dylib 0x93701000 - 0x93721fff com.apple.DirectoryService.Framework 3.1 /System/Library/Frameworks/DirectoryService.framework/Versions/A/DirectoryService 0x95040000 - 0x9506ffff libssl.0.9.7.dylib /usr/lib/libssl.0.9.7.dylib 0x95784000 - 0x957acfff libcurl.3.dylib /usr/lib/libcurl.3.dylib ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=42395&edit=1
