Here's a chunk of the top from my server:

PID    USER      PR  NI  VIRT  RES  SHR S %CPU %MEM      TIME+  COMMAND    
18878  www-data  20   0  200m  13m 4704 S    0  0.2    0:00.07  apache2 
12374  root      20   0  197m 9460 4480 S    0  0.1  21212906w  apache2 
9136   root      20   0 79100 3488 2716 S    0  0.0  54518724d  sshd

I know the TIME+ means the total CPU time the task has used since it started. But in the above output, I simply couldn't understand what 21212906w and 54518724d mean? some considerable no of processes are showing the TIME+ with w and d prefixed.
What does this mean? Is the server in trouble?

Just to let you know - the server uptime is 4days.

EDIT:
- I can guess these refer week and days. If so why is it so large considering the uptime?
- The server has 8 cores.

weeks and days

And it looks to me like there's a bug in your version of top, or the kernel, or something... that it's showing bogus numbers there.

  • Yes, but why are they so high?

  • It looks to me like a bug somewhere. I've seen things like that occasionally (and rarely). Rebooting usually clears the bogus values--in this case restarting the offending processes probably would, too.

  • Yea, I have guessed it, week and days, but why are they so high considering my uptime?

    Another option is that you have 37122585 CPU cores that have been running constantly since you rebooted 4 days ago, giving you 21212906 weeks of CPU usage... but I'm guessing that's not the real explanation :)
