Hey there, I have been asked to help a friend whose system is used as a VPN hub.
It used to be an older OpenBSD, possibly 4.5 or 4.6, and he got many kernel panics around some buffer routines (possibly mbuf) that led to disk corruption. It's now OpenBSD 4.8 amd64, and if the system has transit traffic - going from one leaf through the hub to another - in excess of 100MB at 200kB/s or more, the system stops responding to network traffic for a minute or three. During this time, it becomes unpingable, and the VPN basically stops working temporarily. Often it will start up again, but if the connection is lossy (like a wifi connection), then it sometimes won't recover. Before I investigate further, does anyone have a clue as to what my be going on here? If not, what would be the suggested method for investigating? -- Effing the ineffable since 1997. | http://www.subspacefield.org/~travis/ My emails do not usually have attachments; it's a digital signature that your mail program doesn't understand.
