() (gdb) Previous Comments: ------------------------------------------------------------------------ [2009-05-06 09:56:09] lbarn...@php.net Thank you for this bug report. To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. A gdb backtrace would be helpful. Allow your apache user to generate large enough core files, remove mod_backtrace, and wait for core files to appear. Then load them in gdb and send a gdb backtrace. ------------------------------------------------------------------------ [2009-05-06 09:18:03] jimbobpalmer at gmail dot com Do you need any more information? ------------------------------------------------------------------------ [2009-05-05 20:44:17] jimbobpalmer at gmail dot com [Tue May 5 18:12:50 2009] pid 9925 mod_backtrace backtrace for sig 11 (thread "pid" 9925) [Tue May 5 18:12:50 2009] pid 9925 mod_backtrace main() is at 8066050 /usr/lib/apache2/modules/mod_backtrace.so[0xb7b6ba9a] /usr/sbin/apache2(ap_run_fatal_exception+0x3f)[0x80827ef] /usr/sbin/apache2[0x8082be8] [0xb7f81400] /usr/lib/apache2/modules/libphp5.so(apply_config+0xa9)[0xb7670f6f] /usr/lib/apache2/modules/libphp5.so[0xb767031e] /usr/sbin/apache2(ap_run_handler+0x57)[0x807a127] /usr/sbin/apache2(ap_invoke_handler+0x91)[0x807d4b1] /usr/sbin/apache2(ap_process_request+0x196)[0x80887e6] /usr/sbin/apache2[0x80857d8] /usr/sbin/apache2(ap_run_process_connection+0x57)[0x80814b7] /usr/sbin/apache2[0x808e6ac] /usr/lib/libapr-1.so.0[0xb7d91e8e] /lib/libpthread.so.0[0xb7d1e19b] /lib/libc.so.6(clone+0x5e)[0xb7ca286e] [Tue May 5 18:12:50 2009] pid 9925 mod_backtrace end of backtrace (gdb) bt #0 0xb7f81424 in __kernel_vsyscall () #1 0xb7d2565b in read () from /lib/libpthread.so.0 #2 0x080906e4 in ap_mpm_pod_check () #3 0x0808ea35 in ??
