The Postfix SMTP client is misconfigured. You can find out more with:

    egrep '(warning|fatal|panic):' /var/log/maillog

Instead of /var/log/maillog, specify whatever is appropriate
for your system.

This is not a Postfix problem - your kernel is hosed. The above
egrep command should give you a ton of warnings and error messages.
