Hello, I'm having an issue where swap fills to 100% (0Kb free) after running applications such as openoffice and chrome/firefox but does not decrease substantially when the applications are closed. Ultimately when swap reaches 100%, browser plugins start crashing (java, flash).
The configuration is a mostly out-of-the-box fat-clients (32Bit 3.2Ghz 512MB intel video systems) with a Ubuntu 10.04 Lucid image I built with the --fat-client option of ltsp-build-client on a 64Bit Server. I've made no customizations is Lts.conf. Thank you for your support, dmesg of a firefox crash: [ 791.900521] 67650 total pagecache pages [ 791.900523] 3714 pages in swap cache [ 791.900526] Swap cache stats: add 45890, delete 42176, find 2827/4388 [ 791.900529] Free swap = 20kB [ 791.900531] Total swap = 124688kB [ 791.902305] 128768 pages RAM [ 791.902308] 0 pages HighMem [ 791.902310] 4080 pages reserved [ 791.902313] 98904 pages shared [ 791.902315] 86898 pages non-shared [ 791.902319] Out of memory: kill process 2105 (run-mozilla.sh) score 95346 or a child [ 791.902325] Killed process 2122 (firefox-bin) [ 791.912197] firefox-bin invoked oom-killer: gfp_mask=0x200da, order=0, oom_adj=0 [ 791.912203] firefox-bin cpuset=/ mems_allowed=0 [ 791.912208] Pid: 2133, comm: firefox-bin Not tainted 2.6.32-24-generic #42-Ubuntu dmesg of Java crash (in chrome) [ 4227.264993] Swap cache stats: add 87890, delete 87714, find 9497/15136 [ 4227.264996] Free swap = 0kB [ 4227.264999] Total swap = 124632kB [ 4227.267225] 128768 pages RAM [ 4227.267230] 0 pages HighMem [ 4227.267232] 4131 pages reserved [ 4227.267235] 100756 pages shared [ 4227.267238] 94391 pages non-shared [ 4227.267244] Out of memory: kill process 2609 (chromium-browse) score 987621376 or a child [ 4227.267250] Killed process 2619 (java) [ 4333.230684] chromium-browse invoked oom-killer: gfp_mask=0x280da, order=0, oom_adj=10 [ 4333.230692] chromium-browse cpuset=/ mems_allowed=0 [ 4333.230698] Pid: 2705, comm: chromium-browse Not tainted 2.6.32-24-generic #42-Ubuntu -- Nick Fenger -Information Technology Trillium Charter School 5420 N.
