Subject When do processes need to be killed?
Date Wed, 05 Jun 2002 15:41:33 GMT
I'm a relative newbie on Apache.  We're running Linux 7/Apache 1.3.12.
Lately I've noticed there's a process (see below) called CANamingAdapter
that seems to keep running up CPU time.  The process itself is a ColdFusion
server process that controls the data store for application management
features.

I've killed the process using kill -9, but it immediately comes back under a
different PID and then keeps running up time.  It's not taking up much %CPU
or %MEM, so I'm not certain how to interpret the high number under TIME.

It seems most of the documentation I've read discusses how to kill
processes, but not if/when they should be killed.  Any
suggestions/help/direction would be most appreciated.

(I apologize if the table below doesn't render correctly on your screen; it
is best viewed as plain text).
