Date: Wed, 2 Sep 2009 12:32:15 -0400 From: Adayadil Thomas <adayadil.thomas@...il.com> To: linux-kernel@...r.kernel.org Subject: LowFree pattern Greetings. I am running a centos linux with 2.6.20 version kernel. The system has 1G of RAM. As time goes by the LowFree becomes really low. Right now it shows 137M .. but it goes as low as 8M or so The command - echo 3 > /proc/sys/vm/drop_caches brings back the LowFree to way up high. The question I have is whether the system by itself release the cache (drop cache) automatically to maintain a reasonable LowFree? Is this configurable? Any information or help is much appreciated. cat /proc/meminfo MemTotal: 1034788 kB MemFree: 138240 kB Buffers: 99260 kB Cached: 177776 kB SwapCached: 51740 kB Active: 605172 kB Inactive: 113572 kB HighTotal: 130720 kB HighFree: 252 kB LowTotal: 904068 kB LowFree: 137988 kB SwapTotal: 1048568 kB SwapFree: 976332 kB Dirty: 380 kB Writeback: 0 kB AnonPages: 441348 kB Mapped: 15540 kB Slab: 146088 kB SReclaimable: 104288 kB SUnreclaim: 41800 kB PageTables: 1596 kB NFS_Unstable: 0 kB Bounce: 0 kB CommitLimit: 1565960 kB Committed_AS: 590576 kB VmallocTotal: 114680 kB VmallocUsed: 15052 kB VmallocChunk: 99348 kB -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
