From the fcnlt(2) manual page: Note that flock(2) and fcntl(2) locks may be safely used concurrently. That's why I think that it is a bug in flock() or fcntl() implementation. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
