Has anyone noticed a memory leak in Kernel 2.4.2. Just upgraded to 256megs and still using the swap file. I didn't think that would happen unless I ran a bunch of programs at the same time. -- Thank you. ----------------------------- Gary A.

I've noticed this on all kernels I've used with any Linux distro. I have 256 megs on my main box as well and it seems that some swap is _always_ used. I believe this is normal behaviour because of the Linux memory model (someone else is welcome to correct/expand on this - my knowledge of this area is pretty sketchy). However, use of swap seems to be minimal if you have sufficient RAM. Don

I install Gnome 1.4 and playing video games has gotten to be a problem because the fps has dropped. Moreover, right arfter a reboot I tried to login into my user acct (only had one) and the /home/<user> directory turned into a file (hence no user login into /home/<user>) and in logged me into /. Even more of a pain, the former directory now file is dated as being created on 1970-10-13 with owner under a root querry as ??? and the same for grp at 256,8.kb. When querried under my new user acct it reads as user=383 and grp=446. I regret ever having installed the evil Gnome (and Nautilus - Big Deal). I have many unaccouted for resource use and KDE takes longer to load (except under /root). Bad coding?? On Sunday 13 May 2001 19:31, Ben Rosenberg wrote:

I will say this. I use to be a big Gnome advocate. I am not anymore. I just don't think it's as stable or put together as well as KDE2. I have been using KDE2 since last August and too tell you the truth..I don't miss Gnome at all. I still use some g programs such as gFTP, GIMP, Jpilot..but I haven't fired up Gnome as a desktop for months. KDE2 is damn nice.

I have some kind of memory leak problem too. Generally once a day, my hd will start thrashing, and eating up CPU resources until it is impossible to even run a "killall" command. It always ends in rebooting. -Tim -- ----------------------------------------------------------------- Timothy R. Butler Universal Networks Information Tech.

Hi Ben,
I would carefully examine the processes that are running at the time this occurs. It seems very strange that I haven't see this issues with the same kernel.
I think it might be something to do with Gnome's Medusa (I have a failed Gnome 1.4 install from a few weeks back) thingy, if that's possible. I noticed Medusa is setup to run via cron several times a day, and if I understand right, it would be accessing the hard drive. Also, pecularly, "find" startup a few minutes ago, and just started searching for who knows what, eating between 6-14% of my CPU resources until I killed it. Any suggestions?

"pstree" will show you a formatted list of the processes and their parents, so you can see what program is running find. "ps auxwww | grep find" will give you the entire find command line, how long it's been running, how big it is in memory, and the percentage of memory and CPU that it's taking up. For memory leaks, "ps auxwww | less" is your friend. Look for things taking up large amounts of memory that have been running for a while. -tara
