Need explanation of 'who -d' output
Can someone tell me what the output of 'who -d' is ?
What's causing the process in the list to be there ?
What can be done to get rid of / fix those process ?
Are those process simple problems, important or urgent onces ?
I am asking because while looking for another 'who' option, I saw that '-d' one and when I tried it it listed close to 50 process in it on a server that has been rebooted less then one month ago. From a Google search I see that they are somekind of dead process left from init/users (???) but do not fully understand what they are, where they come from, if they are normal and what can be done about them.
