I’m new to server administration. Using Debian 8, a process called atd is consuming 99% of cpu. From googling I found out that atd is a job scheduler, but I didn’t set up any. I just have apache 2 and tomcat 8 running with a java web app. Atq call is also not listing any jobs. Where can I check for logs/ how to troubleshoot?

Consider the possibility that your server may be compromised. – Michael Hampton Dec 04 '17 at 23:02

I think so. When I shutdown apache2 and kill the process, it doesn't respawn. else it respawns. It is using a config file called mgeflshghx, but Im not able to find it using locate cmd – Cybermonk Dec 05 '17 at 05:16

You may figure out what atd does by checking which files it uses.
ps aux | grep atd
daemon 778 0.0 0.2 26044 2120 ? Ss 22:03 0:00 /usr/sbin/atd -f
→ PID of atd = 778
lsof -p 778
