Previous Comments: ------------------------------------------------------------------------ [2012-05-23 18:20:01] fat@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. I can't do anything w/o a coredump. You should check your ulimits configuration, the directory where FPM children process are in (chdir FPM parameter), the rights of this directory and ensure rlimit_core FPM parameter is not set (to use default ulimit values). ------------------------------------------------------------------------ [2012-04-10 14:54:02] eugene at zhegan dot in Description: ------------ I use an nginx + php-fpm installation. Php-fpm is installed form ports. The problem is, that php-fpm children sometimes (not always) got signal 11 when the master process attempts to rotate em: [10-Apr-2012 20:46:30.072189] DEBUG: pid 14165, fpm_got_signal(), line 72: received SIGCHLD [10-Apr-2012 20:46:30.072278] WARNING: pid 14165, fpm_children_bury(), line 252: [pool www] child 14590 exited on signal 11 (SIGSEGV) after 121.434207 seconds from start Seems like this doesn't affect the production process, but anyway this bothers me and I think you will agree that bugs should be attempted to be fixed. I would be really glad to present you a backtrace, but unfortunately I don't see any corefiles anywhere. Core dumps are enabled, even for suid/gid processes: # sysctl -a | grep core kern.corefile: %N.core kern.nodump_coredump: 0 kern.coredump: 1 kern.sugid_coredump: 1 debug.elf64_legacy_coredump: 0 debug.ncores: 5 debug.elf32_legacy_coredump: 0 But still no cores. Test script: --------------- I don't think this is relatred to some particular script. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61689&edit=1
