Packet drops

Rune
Hi there.

I have a strange problem on my astaro box (vers. 6.004). There seems to be a serious packet drop, but there appear no errors when I run ifconfig. First I thought it was the switch, so I changed that. Then I changed the cables and finally the hole server (I had a spare:-), but no change. Ping tells me that I have a packet drop at 10 to 60 % on all nics. Both internal and external.
The server is a Dell Poweredge 1750 with broadcom nics.

Any suggestions?

Regards
Rune

    Please provide the hardware configuration of the box. You might want to check and see if all cards have been assigned an IRQ.

    Hi Ian.

    Hope this is what you want:

    Ifconfig:

    Code:
      
    eth1      Link encap:Ethernet  HWaddr 00:0F:1F:67:3B:6F
              inet addr:212.88.XXX.XXX  Bcast:212.88.XXX.XXX  Mask:255.255.255.248
              UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
              RX packets:874604 errors:0 dropped:0 overruns:0 frame:0
              TX packets:558363 errors:0 dropped:0 overruns:0 carrier:0
              collisions:3 txqueuelen:1000
              RX bytes:1048203491 (999.6 Mb)  TX bytes:101824700 (97.1 Mb)
              Interrupt:201


    Ethtool:
    Code:

    Settings for eth1:
            Supported ports: [ MII ]
            Supported link modes:   10baseT/Half 10baseT/Full
                                    100baseT/Half 100baseT/Full
                                    1000baseT/Half 1000baseT/Full
            Supports auto-negotiation: Yes
            Advertised link modes:  Not reported
            Advertised auto-negotiation: No
            Speed: 100Mb/s
            Duplex: Full
            Port: Twisted Pair
            PHYAD: 1
            Transceiver: internal
            Auto-negotiation: off
            Supports Wake-on: g
            Wake-on: d
            Current message level: 0x000000ff (255)
            Link detected: yes


    As you can see I have tried to force the nic and the switch into 100fdx, instead of autoneg. I thought that might be the problem. However that was not the case.

    What else do you need?
