Message-ID: <20041008014151.26e17547.akpm@osdl.org> (raw)
I just booted my main workstation into 2.6.9-rc3-mm3 (approx).
fetchmail broke. It's fetching mail from localhost (ssh port-forwarded to
remote servers) and then for some reason it wants to open an SMTP
connection to localhost. It was failing, some error message about that
SMTP connection.
While I was poking at it, it started to work. `uptime' said 6 minutes. So
I'd be suspecting that there's a jiffy wrap bug in TCP-to-localhost
introduced since 2.6.9-rc3.
I rebooted to do more diagnosis and the damn thing worked fine.
I can't see anything suspicious in the post-rc3 net/ diff. But if anyone
has fiddled with time-related things in networking, please double-check
your work?
