It mostly appears when I download files using bittorrent or other large file. I have a phone modem based Internet access using Home Internet Solution (http://en.wikipedia.org/wiki/Home_internet_Solution). I use Debian testing, Linux vanilla version: 2.6.21-rc6 (however I noticed that problem since Linux ver. 2.6.15, doesn't matter if that was vanilla kernel or from Debian distro), Here my sys info: Linux mars 2.6.21-rc6 #3 Sat Apr 7 16:11:12 CEST 2007 i686 GNU/Linux Gnu C 4.1.2 Gnu make 3.81 binutils 2.17 util-linux 2.12r mount 2.12r module-init-tools 3.3-pre2 e2fsprogs 1.40-WIP xfsprogs 2.8.11 PPP 2.4.4 Linux C Library 2.3.6 Dynamic linker (ldd) 2.3.6 Procps 3.2.7 Net-tools 1.60 Console-tools 0.2.3 Sh-utils 5.97 udev 105 Modules Loaded nvidia vmnet vmmon nfs nfsd exportfs lockd nfs_acl sunrpc button xt_TCPMSS xt_limit xt_tcpudp nf_nat_irc nf_nat_ftp iptable_nat iptable_mangle ipt_LOG ipt_MASQUERADE nf_nat ipt_TOS ipt_REJECT nf_conntrack_irc nf_conntrack_ftp nf_conntrack_ipv4 xt_state nf_conntrack nfnetlink iptable_filter ip_tables x_tables ppp_async ipv6 ppp_generic slhc xfs eeprom w83781d w83627hf hwmon_vid i2c_isa ide_generic parport_pc parport rtc floppy serio_raw pcspkr psmouse i2c_viapro snd_via82xx snd_ac97_codec ac97_bus snd_pcm snd_timer snd_page_alloc snd_mpu401_uart i2c_core via_ircc snd_rawmidi snd_seq_device via_agp agpgart snd irda crc_ccitt soundcore evdev ext3 jbd mbcache usbhid ide_cd cdrom ide_disk generic uhci_hcd usbcore via82cxxx ide_core e100 mii thermal processor fan If there are needs for more info, don't hesitate to ask.
