And the percentage use of memory grows up from 9.6 % to 10.5 % so it seems, that this program has any lack of memory. after starting, the connection is coming up, and I cut the connection after one minute, so I had the same values for each test.

Without this program the system does NOT have any problem with memorylacks. hope, this is a useful startpoint to get rid of this weird problem. Hope - anybody can help. the version of control-center is : control-center-1.4.0.1-2mdk net_monitor seems to be a part of control-center, because n rpm -q net_monitor fails. maybe, there is an updated control-center without this bug ? thanks for helping and give some hints bye hans Want to buy your Pack or Services from MandrakeSoft?

Re: [expert] memory problems with pptp-connection
Hans could you have top running on this box. Then as it starts to slow down, grab a copy of top and post it to the group. Top will tell you what the process is that is consuming more and more memory and CPU kill that process if you can to restore things to normal without a reboot. Again posting top will help us in finding out what is causing your problem.

[expert] memory problems with pptp-connection
hi list, have a mdk8.0-box and a pptp-connection. my box is running over 24 hours a day. everytime I'm running "Mandrake-Control-Center and there the connection for internet over pptp, the memory becomes slower and slower, equally, if the connection is on or off. After a few hours every action with the mouse takes minutes - in the range of 1 to 240. That is really crazy. So I'm hoping,now, there is anyone on this list, who could giove me a hint or as experiences with such a behavior. Have 128 MB RAM, so it should be enough for running linux with only X, mailbox, mozilla and sometimes kwrite - nothing else. Looking in the memory-management, the memory is ALWAYS USED AT ABOUT 99 % - FROM STARTING THE X-SESSION to the end. It is really very very horrible to work with such a big behavior.

I don't see how the swap partition couldn't be found -- apart from not properly listing it in /etc/fstab of course. It's either there or not there, and in my experience it is never just 'sometimes' there. I don't use pptp, but maybe there is something amiss there -- have you tried 'top' to see what processes are eating up the RAM? There may be other things besides pptp that are eating memory. In particular, jabber if instaled is a big hogger of memory. But then again, you maybe didn't install that. Your memory report is about average but that is going to vary over time, and over time some of that swap should be used. If 'free' reports 0 available for swap then you may not have it properly attached. What does 'w' indicate? High load average could also be a cause for slow responses between commands. If yours is a memory issue, does the disk get used a lot (indicating heavy swapping)? Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com
[expert] memory-problems
hi, have detected a memory-problem on my mdk8.0 box. have installed for a few weeks now 256 MB RAM, upgraded from 64 MB. Now, that I have the 256 MB RAM, the system sometimes runs out of memory. Results are : sometimes, the swap (=289 MB) couldn't be found the memory-used field shows as follows : memory total: 255,81 MB free: 6,52 MB shared memory : 0 Buffered: 35,1 MB total swap : 305 MB free swap : 305 MB after calling pptp two- or three times between a short time the swap couldn't be found, and the system takes a very long time for EVERY action, I than make. Sometimes I get a lot of kernel-messages, sometime nothing, and the system stucks. Today in the morning - I restarted the system after a crash in yesterday, but no errormessages of the crash I could find now. Before I got the adsl-box, I doesn't make experiences with ANY crash, now I have it sometimes 1 time and sometime 5 times a day. A test I made for 3 days - have deinstalled and deleted the complete pptp-adsl-fr-1.0.2-7mdk - and had NO crashes. Now, I reinstalled it, and the crashes are back. Now my questions : is this a really known behavior ? is there a bugfixed pptp rpm available ? which other possibilities I have to get rid of this weird thing ? Your hints and helps are really very welcome ! thanks in advance bye hans Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com

The "mem" graph has four colors green(user+sharedlibs), orange(file buffer cache), red(paging cache), and the background color (unused memory). Green memory is the stuff that is actively being used by applications, orange and red is memory used to improve performance. When new apps load or kernel mallocs occur and there is no free memory, orange and red memory is used and "converted" to green. And when the entire bar is green and more memory is needed paging will begin and swap will start to grow. I have 640M in my desktop and run vmware so the right side of my mem bar is always red (vmware keeps as much of the windows virtual memory space in the page cache as possible). But I can still run new Linux apps with no problems. duane

Linux doesn't like to see free memory. Unused memory is wasted memory, not available resources. And most of the buffers are read. Write buffers are not usually First-In First-Out. There is a little intelligence in the filesystem that performs writes to physically close areas of the disk at about the same time, even if some scattered ones are delayed to the next available cycle, but you are likely to find most of the memory in use at all times. Also, some buffers are just areas of memory temporarily reserved for that purpose until some running program needs more space and requests it with malloc(). Civileme

(Sync, will, of course, help greatly with that ratio of read-to-write buffer use ;-). On a side note, I had a sparc once with like 256 meg of ram, and I was doing network performance tests. I did an ftp to myself to see what the networking overhead was. Wrote the numbers down, then for some reason did it again. YOW! the numbers like tripled or more (I forget the exact increase). Then I realized what I'd done - I'd just loaded the cache with the data on the first run, then used THAT data the second run. Which gave me a better idea of network and processing overhead without disk delays, which was interesting... Anyway, I would not be surprised to find that having all that buffer space IMPROVES your ability to get (write) data to the disk quicker, since your chances of having a cache hit go up with more stuff in the cache, so your disk is more free to go write the pending writes. (Tell ya what - I'll take some of that ram from you, then you won't have so much buffer space ;-) So (pending correction by someone who REALLY knows ;-), you're probably better off with all that 'spare' memory. And I don't know if you can tell the kernel (or whoever) to NOT use so much free space for buffers - anyone know if I'm wrong? just my $.02 - and you KNOW what you paid for it! ;-) rc Rusty Carruth Email: [EMAIL PROTECTED] or [EMAIL PROTECTED] Voice: (480) 345-3621 SnailMail: Schlumberger ATE FAX: (480) 345-8793 7855 S.

[expert] Memory problems
Hi, I have noticed that my linux box is using a whole lot of physical memory. I have about 672MB on my box and even if I go to runlevel 1 and unload all the modules and unmount all the filesystems, it still is using almost all the memory. This is happening from Mandrake 7.1 and still happens on 7.2. I'm using kernel 2.2.17. Does anyone now if there is a memory leak, or a way to see where my memory is going to, besides using the top and free commands? Thanks, Luis

Re: [expert] Memory Problems
Gary, If you chose "lilo" and not "grub" when you installed, try this: (you will need root access) in a teminal cp /etc/lilo.conf /etc/lilo.conf.old edit /etc/lilo.conf look for a line that says "default" and note it's value (probably "linux"). Then look further down in one of the "image" sections for a "label" that is equal to that value. You have found the default kernel. You should also see "root" and "read-only". In that section there may be an "append" line. This is where you give your kernel directives when it boots. If there is no "append" you will have to create it. You want something like this: append="mem=128M" If there was already an append line, just add mem=128M inside the quotes with only a space between. For example: append="hdc=ide-scsi mem=128M" Save your work. Now open a terminal and type "lilo" and hit return. You should get something like the following: Added windows Added floppy Added linux * If something goes wrong in a terminal type: cp /etc/lilo.conf.old /etc/lilo.conf and try again. The next time you reboot the kernel should recognize all 128M of your memory. Check this by typing "free". You should see 127... under total. there is more info in the man pages. man lilo.conf man lilo pelon On Fri, 04 Aug 2000, you wrote: > I have Linux-Mandrake version 7.1 Install on my machine which has an AMD > process, ASUS motherboard and 256 MB of Ram.

RE: [expert] Memory Problems
Gary, I had the same problem on my Athlon 900Mhz box which had 128 Megs of pc133. Well some how the bios fried on me (NOTE: remind me not to do that again) After returning the motherboard to the manufacture and getting a different one with a different cpu 1Ghz :) with the same ol' drives and cards that I used before Linux was able to see all 128 megs. I also did not reinstall Linux, just hooked everything up to the new motherboard. (and yes I did reinstall and recompile my kernel later on) Which leads me to think that the problem was in the motherboard. Hopefully this puts you on the right path.
