Kept getting warnings about mdir files being changed so copied. Got .lock in procmailrc so maybe this one is done. At least, the error message suggested using lock files (which I thought I had). Now for the expiring/disconnecting/reconnecting eth0. This is operating off a router. I went through the router's configuration, saw nothing about this. So what can I do in any of the Debian network conf files to prevent the disconnect on expire?
