I have a set of computers that seem to have memory leak under 2.6 kernels (2.6.9 and 2.6.10)
The set of machines that suffer this memory leak are the ones using ICH5 SATA and Broadcom gigabit (tigon3) on PCI Express, as opposed to other machines with IDE and Intel gigabit. Both sets of machines use hyper threading. On all machines, the memory report below is after restarting all but init processes, so memory consumed by applications is less than 50 MB. /proc/meminfo just after booting: MemTotal: 906784 kB MemFree: 859228 kB Buffers: 1852 kB Cached: 15624 kB SwapCached: 0 kB Active: 27600 kB Inactive: 10640 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 906784 kB LowFree: 859228 kB SwapTotal: 0 kB SwapFree: 0 kB Dirty: 28 kB Writeback: 0 kB Mapped: 21492 kB Slab: 5640 kB CommitLimit: 453392 kB Committed_AS: 32532 kB PageTables: 80 kB VmallocTotal: 122804 kB VmallocUsed: 8160 kB VmallocChunk: 114416 kB /proc/meminfo after several days of intense activity (after restarting all user land processes except init): MemTotal: 906784 kB MemFree: 438796 kB Buffers: 9304 kB Cached: 14088 kB SwapCached: 0 kB Active: 273772 kB Inactive: 179304 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 906784 kB LowFree: 438796 kB SwapTotal: 0 kB SwapFree: 0 kB Dirty: 40 kB Writeback: 0 kB Mapped: 39700 kB Slab: 11256 kB CommitLimit: 453392 kB Committed_AS: 55308 kB PageTables: 120 kB VmallocTotal: 122804 kB VmallocUsed: 8160 kB VmallocChunk: 114416 kB Hardware of boxes having memory leak problems: 8086 Intel Corporation 2580 915G/P/GV 0 Host Bridge / DRAM Controller 8086 Intel Corporation 2581 915G/P/GV, 925X/XE? 0 Host-PCI Express Bridge 8086 Intel Corporation 2582 82915G B Graphics device 8086 Intel Corporation 2782 0 8086 Intel Corporation 2660 82801FB/FR/FW/FRW 0 PCI Express Port 1 8086 Intel Corporation 2662 82801FB/FR/FW/FRW 0 PCI Express Port 2 8086 Intel Corporation 2658 82801FB/FR/FW/FRW 15 USB UHCI Controller 8086 Intel Corporation 2659 82801FB/FR/FW/FRW 16 USB UHCI Controller 8086 Intel Corporation 265A 82801FB/FR/FW/FRW 12 USB UHCI Controller 8086 Intel Corporation 265B 82801FB/FR/FW/FRW 17 USB UHCI Controller 8086 Intel Corporation 265C 82801FB/FR/FW/FRW 9 USB 2.0 EHCI Controller 8086 Intel Corporation 244E 82801BA/CA/DB/DBL/Ex/Fx/FRW, 6300ESB 0 Hub Interface to PCI Bridge 8086 Intel Corporation 266E 82801FB/FR/FW/FRW A AC '97 Audio Controller 8086 Intel Corporation 2640 82801FB/FR 0 LPC Interface Bridge 8086 Intel Corporation 266F 10 8086 Intel Corporation 2651 82801FB/FW 14 SATA Controller 8086 Intel Corporation 266A 82801FB/FR/FW/FRW A SMBus Controller 14E4 Broadcom Corporation 1677 BCM5751 10 NetXtreme Gigabit Ethernet PCI Express Hardware of machines with no memory leak problems: 8086 Intel Corporation 2570 82865G/PE/P, 82848P 0 DRAM Controller / Host-Hub Interface 8086 Intel Corporation 2572 82865G B Integrated Graphics Device 8086 Intel Corporation 24D2 82801EB/ER B USB UHCI Controller #1 8086 Intel Corporation 24D7 82801EB/ER A USB UHCI Controller #3 8086 Intel Corporation 24DE 82801EB/ER B USB UHCI Controller #4 8086 Intel Corporation 24DD 82801EB/ER 9 USB EHCI Controller 8086 Intel Corporation 244E 82801BA/CA/DB, 6300ESB 0 Hub Interface to PCI Bridge 8086 Intel Corporation 24D0 82801EB/ER 0 LPC Interface Bridge 8086 Intel Corporation 24DB 82801EB/ER 12 EIDE Controller 8086 Intel Corporation 24D3 82801EB/ER 5 SMBus Controller 8086 Intel Corporation 24D5 82801EB/ER 5 AC'97 Audio Controller 8086 Intel Corporation 100E 82540EM 12 Gigabit Ethernet Controller - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
