Running 13.1-RELEASE with everything installed from packages and aslr enabled, apache24 will core dump on a graceful restart after installing php81-extensions. Start with apache24, php81 and mod_php81 installed /usr/local/etc/rc.d/apache24 start apache is running /usr/local/etc/rc.d/apache24 graceful apache is still running Then install php81-extensions: /usr/local/etc/rc.d/apache24 stop pkg install php81-extensions /usr/local/etc/rc.d/apache24 start apache is running /usr/local/etc/rc.d/apache24 graceful kernel: pid 2122 (httpd), jid 0, uid 0: exited on signal 11 (core dumped) This is with using all the default conf files. If I disable aslr it works fine. I'm enabling aslr by adding these lines to /etc/sysctl.conf and rebooting. kern.elf32.aslr.enable=1 kern.elf32.aslr.pie_enable=1 kern.elf32.aslr.honor_sbrk=0 kern.elf64.aslr.enable=1 kern.elf64.aslr.pie_enable=1 kern.elf64.aslr.honor_sbrk=0 This is the first time I've tried enabling aslr so maybe I'm doing something wrong.
