I have not seen segfaults anywhere = else on this system. It is plausible that apache is simply reporting segfau= lts from php. This is why I think something nefarious is happening within t= he ports. I am back on site now and, with some help from grep, established that the *only* Segmentation faults logged are associated with httpd or apache24. Is it really plausible that this can be hardware?
