I'm trying to update apache and mod_security. Apache is compiling fine. The problem is with mod_security. It compiles with both xlc and gcc; however, when I start apache I get the following error: # /usr/IBM/WebSphere/apache2/bin/apachectl start -f conf/httpd_internal.conf /usr/IBM/WebSphere/apache2/bin/apachectl[81]: 21561378 Memory fault(coredump) The dbx dump of the core file: # dbx bin/httpd core Type 'help' for help. [using memory image in core] reading symbolic information ...warning: no source compiled with -g Segmentation fault in mod_security2.register_hooks [/usr/IBM/WebSphere/apache2/modules/mod_security2.so] at 0xd67ed1b8 ($t1) 0xd67ed1b8 (register_hooks+0x38) 801e0000 lwz r0,0x0(r30) I found similar issues in the following link: http://sourceforge.net/mailarchive/forum.php?thread_name=CAHQz1rJ7ahPFHV-WGjqqY8oqD2N_hPukKbTA1yTeQ-u9qFSoQA%40mail.gmail.com&forum_name=mod-security-users However, nothing this thread seems to work. Also, this may be known, but the apache2/Makefile rule install-exec-hook is trying to install mod_security2.so from the destination to the destination. Changed the install to come from .libs/ and the install worked fine... until you start apache ;). Respectfully, Allan Cano |
