Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I inadvertently blocked inbound udp from DNS:53 to box:any and noticed that qpopper (2.53) started creating errant, cpu slowing processes that went away when I opened it back up. I was able to reproduce the behavior repeatedly. Box is 3.3-RELEASE. Is this just a quirk of misconfiguration? Box is running NAT and net is private. Only clients accessing popper are on private net. This is probably an issue more for Qualcomm but I though't I'd check here first. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
