After reading through the comments on the openssl bug report ( http://rt.openssl.org/index.html?q=2305 ) the part about having a Core i7 caught my attention. I am having the same problem but only on one of my servers and not the other; both running 10.04_64 and updated to the same kernel. I have two VMware ESXi servers, one is running quad-core Xeon X5550s and the other is running hex-core Xeon X5650s (same generation as the i7s). I moved the VM that was working from the older server to the new, and when using ssl, Apache started seg faulting, having made no changes to the configuration.
Miroslav Zacek: It sounds like you have found the issue in openssl. Is there any other troubleshooting I can do to help?
