    Hello,

    I have PIII 500 with 1GB of RAM on 4.9-RELEASE
    running Squid 2.5-STABLE4 and I got this error after a
    few hours of Squid running.

    proxy (squid): xmalloc: Unable to allocate 65535
    bytes!

    According to Squid FAQ

    8.7 xmalloc: Unable to allocate 4096 bytes!
    by Henrik Nordstrom

    Messages like "FATAL: xcalloc: Unable to allocate 4096
    blocks of 1 bytes!" appear when Squid can't allocate
    more memory, and on most operating systems (inclusive
    BSD) there are only two possible reasons:

    1. The machine is out of swap
    2. The process' maximum data segment size has been
    reached

    I got 2500MB swap file and isnt used when i try to use
    the cmd top. How do i recompile a kernel with larger
    datasize settings?

    here's the options that i added im my kernel

    maxusers 128
    options USER_LDT
    options DUMMYNET
    options IPFIREWALL
    options IPFIREWALL_VERBOSE
    options IPFIREWALL_VERBOSE_LIMIT=100
    options IPFIREWALL_FORWARD
    options IPFIREWALL_DEFAULT_TO_ACCEPT
    options IPDIVERT
    options HZ=80
    options NMBCLUSTERS=65536

    sysctl.conf

    vfs.vmiodirenable=1
    kern.ipc.maxsockbuf=2097152
    kern.ipc.somaxconn=8192
    kern.ipc.maxsockets=16424
    kern.maxfiles=65536
    kern.maxfilesperproc=32768
    net.inet.tcp.rfc1323=1
    net.inet.tcp.delayed_ack=0
    net.inet.tcp.sendspace=65535
    net.inet.tcp.recvspace=65535
    net.inet.udp.recvspace=65535
    net.inet.udp.maxdgram=57344
    net.local.stream.recvspace=65535
    net.local.stream.sendspace=65535

    loader.conf

    userconfig_script_load="YES"
    hw.ata.wc="1"

    Squid Configuration

    cache_mem 384
