I solved this issue. nginx 0.7.x does not complain about the missing variable secure\_download\_fail\_location. Therefore, when an error occurs in that module, the variable/URL is not found and it segfaults. I believe later versions of nginx complain about the missing variable. – * * * Robert La Ferla VP Engineering OMS SafeHarbor This message (and any attachments) contains confidential information and is protected by law.
