Hi folks, I'm trying to debug an irritating little apache module problem. Periodically httpd is seg-faulting, so I have rebuilt it statically with full debugging flags and no strip options in an effort to find out why. Unfortunately, no core image is being saved when the seg-fault occurs. I have poked around the OS but can't find anything. Core file size is infinite, there is plenty of space. I thought maybe that since it dumps the core in the working directory by default, maybe it didn't have write access. I tried changing the sysctl kern.corefile to /tmp/%N.core but to no avail. I have tried running with the -X flag, but all that does is stall the web server, and the seg-faults stop (perhaps because no requests are getting answered). I'm stuck for ideas now. Is there something I optimized out of the kernel that needs to be in there, perhaps? Some secret flag that only kernel hackers are privy to? If anyone has any suggestions, I'd be very grateful. I really want to get this problem knocked over soon.
