connections to localhost

:Sorry if my description is somewhat vague, but here it is.

:After some uptime I can no longer send mail.

:[murmeldjur//rnyberg]$ ps axlwww | grep sendmail

:[murmeldjur//rnyberg]$ telnet localhost smtp     
:Trying 127.0.0.1...
:telnet: connect to address 127.0.0.1: Operation timed out
:
:It's strange that stopping and starting sendmail don't help,
:but rebooting does.
:
:I also get problem with sshd and X forwarding. Setting the option
:X11UseLocalhost no, makes it work.
:
:I don't know when this behaviour started but it's been so for a while.
:The computer is an SMP machine with sources from Jun 18.

    Ouch.  Well, that looks like a definite networking bug since 
    localhost connections should never time out.  I think we'll have
    to try to fix it before the release :-)
