I have PHP executing as fastcgi via the mod_fcgid module in Apache. I suspect there is a bug in PHP or one of its extensions which causes it to crash with sigsegv, but I cannot get any coredumps. I suspect something is setting coredumpsize to 0 - either Apache, mod_fcgid or PHP.
So the question is: is there a way to set coredumpsize on a running process, with the intention of getting a core dump when it crashes? I already tried setting CoreDumpDirectory in Apache and also configuring apache22limits_args in /etc/rc.conf but without effect.
