Hi During the testing of reflector example, I have got following kernel messages like "bash invoked oom-killer" (see below). Could you explain this (possibly) leak ? Fixes, ideas ? I have searched maillists and seems the leak has been fixed in previous releases. Could you help me, Luca ?
This happened after some intensive tests using pktgen from another machine (about 500 Mbit/s, 64 byte pkts) Bash script periodically called "ethtool -S eth1" to get statistics from ethernet card. After this message ssh session was aborted. I tried to log in again but the system was hanging after login and before password. Neither pings nor logins from console were accepted by it. PF_RING module was loaded with transparent mode=0 BTW, the system hangs on pfcount with PF_RING settings transparent mode=1, TX capturing=1 -- My system : Fedora 8, Athlon64 Duo, 2 GB RAM, Intel 1000/PRO PT, mainboard ASUS M2N-SLI, sata, LVM kernel : [...@recv ~]$ uname -a Linux recv 2.6.26.6-pfring #1 SMP Thu Nov 27 18:14:24 MSK 2008 i686 athlon i386 GNU/Linux driver: [...@recv ~]$ ethtool -i eth1 driver: e1000e version: 0.3.3.3-k4 firmware-version: 5.11-8 bus-info: 0000:02:00.0 BR, Vladimir ----------------------------------------- Dec 11 15:17:43 recv kernel: [PF_RING] Welcome to PF_RING 3.9.0 Dec 11 15:17:43 recv kernel: (C) 2004-08 L.Deri <[email protected]> Dec 11 15:17:43 recv kernel: NET: Registered protocol family 27 Dec 11 15:17:43 recv kernel: [PF_RING] Ring slots 4096 Dec 11 15:17:43 recv kernel: [PF_RING] Slot version 9 Dec 11 15:17:43 recv kernel: [PF_RING] Capture TX Yes [RX+TX] Dec 11 15:17:43 recv kernel: [PF_RING] IP Defragment No Dec 11 15:17:43 recv kernel: [PF_RING] Initialized correctly Dec 11 15:17:43 recv kernel: [PF_RING] registered /proc/net/pf_ring/ Dec 11 15:19:01 recv kernel: [PF_RING] successfully allocated 6434816 bytes at 0xf8b9c000 Dec 11 15:19:01 recv kernel: [PF_RING] allocated 4098 slots [slot_len=1570][tot_mem=643481 6] Dec 11 15:19:01 recv kernel: device eth1 entered promiscuous mode Dec 11 15:19:01 recv kernel: [PF_RING] successfully allocated 6434816 bytes at 0xf91c0000 Dec 11 15:19:01 recv kernel: [PF_RING] allocated 4098 slots [slot_len=1570][tot_mem=643481 6] Dec 11 15:19:01 recv kernel: device eth2 entered promiscuous mode Dec 11 15:27:44 recv kernel: [PF_RING] removed /proc/net/pf_ring/2074-eth1.0 Dec 11 15:27:44 recv kernel: [PF_RING] removed /proc/net/pf_ring/2074-eth2.1 Dec 11 15:28:03 recv kernel: [PF_RING] successfully allocated 6434816 bytes at 0xf8b9c000 Dec 11 15:28:03 recv kernel: [PF_RING] allocated 4098 slots [slot_len=1570][tot_mem=643481 6] Dec 11 15:28:04 recv kernel: [PF_RING] successfully allocated 6434816 bytes at 0xf91c0000 Dec 11 15:28:04 recv kernel: [PF_RING] allocated 4098 slots [slot_len=1570][tot_mem=643481 6] Dec 11 15:28:36 recv kernel: bash invoked oom-killer: gfp_mask=0x40d0, order=0, oomkilladj=0 Dec 11 15:28:36 recv kernel: Pid: 1968, comm: bash Not tainted 2.6.26.6-pfring #1 Dec 11 15:28:36 recv kernel: [<c0466b03>] oom_kill_process+0x42/0x183 Dec 11 15:28:36 recv kernel: [<c0466f41>] out_of_memory+0x157/0x188 Dec 11 15:28:36 recv kernel: [<c0468edf>] __alloc_pages_internal+0x2b5/0x34a Dec 11 15:28:36 recv kernel: [<c0468f8b>] __alloc_pages+0xa/0xc Dec 11 15:28:36 recv kernel: [<c04806c6>] __slab_alloc+0x14c/0x40a Dec 11 15:28:36 recv kernel: [<c0480d31>] kmem_cache_alloc+0x51/0x98 Dec 11 15:28:36 recv kernel: [<c0489cd9>] ?
