It may provide a useful clue. According to "Art Haas" : > I'm running the current BK kernel now, and I'm not seeing the problems > right now because, I found, I do not have some of the IP masquerading > modules installed on my machine. When these modules get installed then > the cvs/rsync problems appear. I do have CONFIG_IP_NF_TARGET_MASQUERADE=y on the system where I'm seeing this, though it's not doing anything just now. Haven't yet made time to see if disabling it improves things ... but if that's a factor, it could explain why more people aren't suffering with this problem. - Dave
