    SubjectMemory leak in kernel 2.0.32pre1.
    The kernel memory leak discussed in some of my previous postings exist in
    2.0.32pre1 too. See erlier posting:
    Date: Tue, 21 Oct 1997 15:57:58 +0200 (CEST)
    Subject: Kernel 2.0.31 memory leak.
    and:
    Date: Mon, 22 Sep 1997 10:05:51 +0200 (CEST)
    Subject: Kernel 2.0.31pre9 memory leak (or where did all the memory go?)

    Here are some example memory statistics:
    4:30pm up 42 min, 13 users, load average: 0.08, 0.06, 0.01
    total used free shared buffers cached
    Mem: 31132 30580 552 23064 4872 13856

    Swap: 66492 0 66492

    There are no processes that eats up this amount of memory. I guess this
    will continue to decrease until no memory is left as it did before... I
    will send a new note when it dies. I will then test 2.0.32pre4 but for two
    other obvious reasons. The problem is, if it still has the the memory
    leak, it will be pretty anoying to reboot every machine after a couple of
    days.

    These five machines acts as terminal servers and have 24 extra
    serialports installed, mostly running pppd. They also have web/mail
    services for the local users (aprox 600 users per machine). Loadaverage is
    around 0.01. They are based around Debian 1.2 + upgrades from 1.3.
    They have very sparce kernel configuration and does'nt use modules.
    I use drivers/net/3c59x.c v0.46C from Donald Becker, to get the Vortex
    card working better.

    Hardware:
    P5/100Mhz processor
    32Mb of RAM
    ASUS P/I-P55TP4XE Mother Board
    1.2Gb QUANTUM FIREBALL1280A EIDE Hard Disk
    On board IDE using DMA
    3*8+2 serialports 16550A UART
    3Com 3c590 Vortex 10Mbps Ethernet PCI card or
    3Com 3c905 Boomerang 10Mbps Ethernet PCI card

    Here is my .config:
    CONFIG_NET=y
    CONFIG_PCI=y
    CONFIG_SYSVIPC=y
    CONFIG_BINFMT_ELF=y
    CONFIG_KERNEL_ELF=y
