Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Hi, We have made some kernel changes. And accordingly we are testing the changes using some user level daemon. After sending some packets, the system hangs. The number of packets sent before the system hangs varies from time to time. Could some body tell me how to know what is happening? How do I find out the reason for hanging? Is there anyway to get such information through some core dump? I have enabled taking dumps and it is dumping when the system panics but not when it hangs. Is memory leakage can cause a system hang? If so how do I find out that there is a memory leakage? thanks --gb To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
