Processes



Hello all

I am wondering, what it means when a process shows up with brackets around its name when I call "ps ax". For example, the sshd here:

  PID TTY      STAT   TIME COMMAND
[snip those procs]
  170 ?        SW     0:01 [sshd]
[snip those procs]

And why does apache create so many instances of itself? I know this can be config'd, but how many are necessary for a fairly small setup?

  PID TTY      STAT   TIME COMMAND
[snip those procs]
  191 ?        S      0:00 /usr/sbin/apache
  201 ?        S      0:00 /usr/sbin/apache
  202 ?        S      0:00 /usr/sbin/apache
  203 ?        S      0:00 /usr/sbin/apache
  204 ?        S      0:00 /usr/sbin/apache
  205 ?        S      0:00 /usr/sbin/apache
  718 ?        S      0:00 /usr/sbin/apache
  719 ?        S      0:00 /usr/sbin/apache
  720 ?        S      0:00 /usr/sbin/apache
[snip those procs]

TIA
Sven
