Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

I keep getting booted out of one of the user account on my Debian Squeeze server. At first I thought that it had something to do with SSH, but it still happens even if I log into another account and then su to the problem account. The first account does not get disconnected.

For example:

good_user@hostname:~$ su problem_user
Password:
problem_user@hostname:/home/good_user$ Killed
good_user@hostname:~$

If I wait about a minute, it always prints Killed and then logs me out. It also kills all of my processes and screen sessions. It does not matter if I run commands or not. I couldn’t find anything in the logs related to this problem.

Any ideas what the problem could be or how to fix it?

If it prints "killed" you received a SIGKILL.

what could cause this is a killall -9 -u youruser that is somewhere in a cronjob or something...

check crontab -l and /etc/cron.d/*

What user is this? A service user or something?

I just created a user to run an application in the background. It is a fresh install of Debian. There is nothing related to killing the user in the cron tab. –  Ian Nov 19 '12 at 2:38
