Stale users and no process

HP-UX B.11.23 U ia64

I've got two users that show in "w" with long idle times but if I search for their processes I find nothing (ps -ef | grep username )

I'm not sure why "w" still sees them and if there is anything (short of a reboot) that I can do to clean them out.

Please cut and paste the output of your w and ps -ef | grep ... commands.

I didn't want some of those specifics out on the 'net but I'll see what I can do with some cut and paste I guess.

Here is more or less what I get with "w" - usernames are changed. It is name8 and name9 that I want to clear up.

 12:07pm  up 337 days,  1:49,  10 users,  load average: 0.03, 0.02, 0.02
User     tty           login@  idle   JCPU   PCPU  what
name1     console      10:19am8088:23                -sh
name2 pts/ta        9:49am    21                natural parm=readonly rdnode=
name2 pts/tb       10:22am  1:44                -sh
name3  pts/tc       12:04pm     2                natural parm=idsparm
name4  pts/te        9:30am  2:37                natural parm=idsparm
me       pts/tf        8:53am                      -sh
name6  pts/th       11:50am    14                natural parm=idsparm
name7  pts/tg       11:45am     5                natural parm=idsparm
name8  pts/t2d       9:54am3339:03                -
name9   pts/t0h       9:49am7825:17

and here is the output of ps -ef | grep name8

me@myserver:/users/sag/prod/reports> ps -ef | grep name8 
me  7845 28284  0 12:09:55 pts/tf    0:00 grep name8

only my grep command comes back. Same result if I search for name9

w reads a file - usually wtmpx. Those are not real processes, ie., if ps does not see them they became defunct and removed. Clearly, they were removed from the process table, but not cleaned up in the utmpx/wtmpx file.

A reboot will remove them, but I don't see what that gains on a production box, other than user complaints. Smilie

Sorry about the lack of tags. I haven't posted in a long time and didn't catch the hint.

We're in the process of closing out the applications on this server and when I'm capturing the user stats every 15 minutes I was just getting annoyed at being over by two no matter the time of day so I thought I'd clean them if it was easy to do. Not worth a reboot though. I can just keep explaining that the 2 users on at 2AM every day are not really there.

Maybe they are just trying to get in some virtual overtime Smilie

Sitting idle for >100 days isn't going to cut it I don't think Smilie
