Re: [newbie] memory: leaks and fragmentations
I think so, check all the service u run. I just use 128Mb, never got like what u got. I monitor my memory used by gkrellm and open bluefish, opera, netscape, xmms, yahoo messenger, prozilla download manager, audio galaxy satellite, and still works fine, with not that much of using memory as u did. It's absolutely not windoze box! Well, yeah gnome is good, but kde has too many thing that much more interesting, like integration of all kde application. Kde is more fancy, but u could use window maker or black box which is lighter. -m- On Monday 03 December 2001 18:12, you wrote: > this has been gone into for ever..but what you are veiwing _Might_ have to > do with the cache use by linux.

After each of these steps, check the resources available in the Resource Meter. Open AbiWord. Open an existing document in AbiWord (which creates a new window). Close that document. Open it, close it, open it, close it, ... After each open close cycle you will notice that fewer and fewer resources are available. Is AbiWord caching the same document multiple times? (If that is the case, it is just as good as a memory leak.) Randy Kramer Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com

Maybe there are different levels of memory leak? In many cases after you shut down a Windows program which continued to use more and more memory, the memory is freed for the OS. Example: (sadly) the recent versions of AbiWord (for Windows) that I've tested have a memory leak. If you invoke AbiWord and then open and close additional windows for documents, more and more memory is used, but not freed up until you close the last AbiWord window, at which point all the memory is restored. (Note: some memory is restored each time you close a document (window), but more and more is locked up until you finally close AbiWord completely. There seem to be other memory leaks that do not restore the lost memory until a reboot. Now that I've written this, I suspect that some of the memory leaks are in the operating system itself and some are in applications, thus making the difference. Maybe Linux (currently) has no leaks in the operating system itself. (But, I'll bet some of the development versions have had leaks.)

Re: [newbie] memory: leaks and fragmentations
yes.. but when that process terminates... the memory should be returned to the system, right? in which case... the OS never lost track of it.

Linux does not appear to make any attempt to stop memory leaks. I wrote a quick program with an infinite loop that dynamically allocated some memory. Watching top, its memory usage climbed dramatically. There's really no way for Linux to know if I really am using that memory or not, so I don't see how it could interfere. Matt _ Do You Yahoo!?

I don't think it is a "memory leak" (this ain't > your win 95 box) I don't think there is anything inherent in Linux which will prevent memory leaks -- it comes down to care and testing by the programmer. AFAIK, memory leaks can be created anywhere C or C++ are used (and probably many other languages). Randy Kramer Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com

So the fact that my memory is nearly full despite most everything being shutdown is not really a concern. I'm still curious about KDE, though. Matt _ Do You Yahoo!?
