John, I have seen this from time to time in various releases; it appears to be the usual race condition in which thread A is supposed to build object <foo>, but is delayed, so that thread B, which depends on <foo>, doesn't find it and fails. I grant you that I haven't tried it after my most recent CVSup run, but I suppose I can. I'll get back to the list in a bit. -- Mike Andrews mikea@mikea.ath.cx Tired old sysadmin since 1964 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
