** Description changed: As soon as I start Ubuntu 12.04.4 LTS with i386 PAE kernel, 8GB memory, GNU/Linux 3.2.0-64-generic-pae i686, cache memory area increases a little by a little, and It consumes at last, a few hours later, 5GB memory. User memory left will become 200MB. I release cache memory by issuing a shell script, cache_release.sh. It is like that : #!/bin/bash /bin/sync /bin/sync /bin/sync /bin/sync /bin/sync /sbin/sysctl -w vm.drop_caches=1 /sbin/sysctl -w vm.drop_caches=2 /sbin/sysctl -w vm.drop_caches=3 I registered this shell script to crontab and I issue this script - command once a hour. + command once a ten minutes. Maybe kernel requires patches.
