RE: cpu used too much
zombie processes are the remains of a process that exited. The reason they hang around is that the parent process didn't do a "wait" on them. As soon as the parent process exits, the zombie should be inherited by init and init will clean them up. Zombie's don't use any cpu and they don't use any memory. The only thing left is the entry in the process table. They don't hurt you except if you fill up the process table with them (in which case you start seeing "cannot fork" errors). I suppose there could be circumstances where you would expect zombies but it is usually considered a bug in the parent process. jim >-- >From: D'jinnie[SMTP:[EMAIL PROTECTED] >Sent: Thursday, March 04, 1999 9:35 PM >To:Debian User List >Cc: The recipient's address is unknown. >Subject: Re: cpu used too much > >speaking of things going into infinite loops and eating up CPU, is there >any way to get rid of zombie processes?

Re: cpu used too much
speaking of things going into infinite loops and eating up CPU, is there any way to get rid of zombie processes?

Re: cpu used too much
OK. It was xosview eating up 87% of my cpu. Now, everthing is back to normal... Thanks.

It's not going to overheat your CPU unless things are broken anyway - your CPU should be able to handle 100% utilisation quite happily. It will keep things warm, but hardworking processors (usually) run hot. What it does do is take resources away from processes that are actually doing useful work, and indcates that something down the line is broken. -- Mark Brown mailto:[EMAIL PROTECTED] (Trying to avoid grumpiness) http://www.tardis.ed.ac.uk/~broonie/ EUFShttp://www.eusa.ed.ac.uk/societies/filmsoc/
cpu used too much...
Howdy Y'all I'm a VB Programmer trying to pick up on Linux & C++... When a program goes into a loop, like when a program crashes, the computer will act strange... Things will be extremely slow, or will not work, etc... If you check with 'top' & see what's eating up your cpu, like Andrei suggested, make sure you know what the process is that is eating up the cpu time... If you are not familiar with it, see what others may know Hope This Helps, Brant Wells

Naturally you should not see CPU working a lot, unless you are, for example, starting Netscape. For example, on my computer CPU load is 5-8% at most, when I'm not doing any compilations/etc. If a process eats up 95% of CPU it means it's crashed. Some processes just don't die quietly when they crash, but go into loop instead, therefor eating all the CPU. What are consequences of that? Anyone? I'd figure heat that builds up will eventually become a problem overheating your CPU, which will result in errors and crashes. So 'top' and see whats causing the problem. THen kill the process, if needed. Andrew --- Andrei S. Ivanov [EMAIL PROTECTED] UIN 12402354 http://members.tripod.com/AnSIv <--Little things for Linux.
