Hi vinvc,

add long option --headers and remove the grep to see the meaning of each column of output

Hi vinvc,

I don't think you can easily show just the 1st line of output, then the rest of the matching lines, but in answer to your question - the column you refer to displays the amount of CPU time a process has consumed since it was started.  If you've not made a typo then I suspect you have a rogue process.

Thanks Steve, i think  i do have a rogue process which i was investigating.
Hi vinvc

Try sending SIGHUP to the process to see if it will restart itself nicely.  Eg. kill -SIGHUP <pid>

Failing that you might want to kill it good and proper, kill -SIGKILL <pid>

Umm, on my Linux system (Fedora Core 4) that column is in the hh:mm:ss format and is the amount of CPU time that daemon has used.  If I see something that has 00:00:25 that means it has used 25 seconds of CPU, if I see 00:35:55 it has used 35 minutes and 55 seconds of CPU.

I can only assume that 19638:35 may mean it has used a LOT of CPU time.  If the task is multi threaded (which Java is) and this is a multi-CPU box, this could be the total amount of CPU minutes (19,638) and seconds (35) it has used.

Is this this a SMP box?
