https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D268318 --- Comment #98 from Mari=C3=A1n =C4=8Cern=C3=BD <majo-bugs.freebsd.org@cer= ny.sk> --- (In reply to Mari=C3=A1n =C4=8Cern=C3=BD from comment #97) I take back my previous comment. Just disabling ASLR does not work for me. = It worked for few `service apache24 reload` calls, but then crashed at midnight when rotating logs. Now it crashes even with `service apache24 reload`. It was crashing with the following backtrace: # lldb --core httpd-26294.core httpd (lldb) target create "httpd" --core "httpd-26294.core" Core file '/tmp/httpd-26294.core' (x86_64) was loaded. (lldb) bt * thread #1, name =3D 'httpd', stop reason =3D signal SIGSEGV * frame #0: 0x0000000801670f90 libgd.so.6 frame #1: 0x00000008022b54f2 opcache.so`___lldb_unnamed_symbol1014 + 66 frame #2: 0x0000000802877586 libphp.so`___lldb_unnamed_symbol8134 + 22 frame #3: 0x0000000802858ee0 libphp.so`zend_llist_apply_with_del + 64 frame #4: 0x00000008027f8d47 libphp.so`php_module_startup + 2343 frame #5: 0x00000008029550e5 libphp.so`___lldb_unnamed_symbol9803 + 21 frame #6: 0x00000008029548c6 libphp.so`___lldb_unnamed_symbol9798 + 118 frame #7: 0x0000000000262271 httpd`ap_run_post_config + 81 frame #8: 0x000000000025d8a5 httpd`main + 2421 frame #9: 0x000000000025cd80 httpd`_start + 256 Moving LoadModule php_module to the top of the list seems to "fix" (workaro= und) the crash. Looks like some bogus pointers. Hard to tell who to blame. If i is a bug in apache or PHP (opcache is a suspect). Would be great if somebody who has experience with apache/PHP debugging on FreeBSD would have a look. I guess = it should not be so hard to pinpoint the issue when it is a reproducible probl= em. I am on a path migrating from mod_php to php-fpm, however despite mod_php b= eing deprecated I do not think it should crash (e.g. the bug might still be pres= ent there and cause different problems). --=20 You are receiving this mail because: You are the assignee for the bug.=
