Hate to tell you but if you find your machine all of a sudden with problems and your network card is in promiscuous mode there is a great chance someone has been messing with your system.
Setting a network card into promiscuous is used to be able to see all the network traffic on that subnet. Which is usefull for password sniffers. You have to have root permissions to set your network card in promiscious mode.
You might want to try and get chkrootkit to scan your system to find out if there are any bogus things on there. And read the securtiy forum to find out what to do if you really have problems.
