Well, I'm not usually so worried about VM but I got to work this moring at 10:15am and with in an hour of logging into my workstation swap usage went from 2M after starting KDE2 to 26M..this isn't right. It never uses this much with 2.4.4 or 2.4.7. I guess I should backdown.. but it's weird that no one else is seeing this behavior.

I had two threads about this a while ago. At first I thought it was X, then perhaps kde or nvidia, but now I don't know anymore. I have a very odd pattern of memory usage, ranging from hardly any used, to 100% of mem+swap followed by system crash (happened three times). I can't track it to any particular app, and all I was told on this list was that I don't know how un*x mm works, and 'it isn't like windows'. If you get any ideas, I'd love to hear about it.

I had never seen a Linux application bring down Linux before either, until netscape. It has completely seized control of my system. No login, nothing, my only alternative was a reboot. Mozilla may or may not be the cause. If it is causing problems, and if you are running bash you have some control over your processes. How much memory, priority, etc. The kernel also has some tuning parameters that might help.

I cannot make any conclusions yet, I can give you the facts. I installed Mantel's kernel 2.4.13-4GB #1 Sun Oct 28 18:58:25 GMT 2001 i586 unknown on my home machine, its uptime is 2 days and it's just 800k of swap. I have 256M physical RAM, I run windowmaker and X 4.0.2. So no strange swap consumption. vmstat reports: procs memory swap io system cpu r b w swpd free buff cache si so bi bo in cs us sy id 2 0 0 832 12364 51248 62596 0 0 3 24 108 152 19 4 77 At work, the kernel is 2.4.4-64GB-SMP #1 SMP Wed Jun 27 08:41:56 GMT 2001 i686 unknown the same X 4.0.2 and windowmaker, the machine has 128M of RAM. Uptime is 9 days, with mozilla 0.9.5 running mostly all that time, I have 105M of swap, and it keeps growing until I restart mozilla. vmstat on this system reports: procs memory swap io system cpu r b w swpd free buff cache si so bi bo in cs us sy id 1 0 0 105400 7848 3844 61008 0 0 3 3 54 34 16 3 27 I can correlate huge swap consumption to mozilla only.

Yes, netscape was the first application to froze Linux system for me. Unfortunately, mozilla does not look better in this respect. -Kastus

Just for informational purposes. I am running SuSE 6.4 with 2.2.19 kernel, X 3.3.6, KDE 1, Mozilla .9.5, with 384M ram and 128M swap. Though Mozilla has crashed many times, it has never crashed Linux on my system, and though it uses more memory than I would think is neccessary (though if it would speed it up its OK), my system uses 0K swap. -- Joe & Sesil Morris New Tribes Mission Email Address: Joe_Morris@ntm.org Web Address: www.mydestiny.net/~joe_morris Registered Linux user 231871 "We can stand affliction better than we can prosperity, for in prosperity we forget God." --Dwight Lyman Moody

I would post the problem to kernel mailing list. There are some very knowledgable people on that list, and it does sound like a kernel problem.

Hi Ben, I am running a vanilla 2.4.13 kernel on a PIII 800 with 384Megs of ram under X 4.1 and Afterstep. I compiled Mozilla 0.95 for the first time a couple of days ago. Next morning whilst running Moz with a number of tabs open my system locked up completely - no keyboard input of any kind possible. After the reboot and running Moz again I noticed that cpu usage was very high - 98% of which was kswapd. I have never seen that before. I have been playing with Moz since then and (whilst I find it slow to load and somewhat unresponsive), the problems have not recurred. I do not regularly monitor swap usage and my experience may or may not be relevant, but I offer it for what it is worth.
