    Networking issues


    Hi guys,

    First post here

    Okay, we are having network issues on 3 of our production servers (Running Oracle)

    We are getting a lot of dropped connections and users are complaining of losing connection to Oracle. Our 1 application servers network service also randomly stop/hangs.

    We have confirmed with our network team that they don't pick up any dropped packets on the switches. We tried switching the mezzanine cards which didn't work. We increased the buffer on the network. We made configurations to the bnx2 drivers as well.

    All 3 servers are running Red hat 5.3 (Tikanga)

    Thanks in advance

    Have you tried applying kernel updates (if you haven't done that already) from Red Hat? I assume here that you have a RHN subscription. There may be a fix to the bnx2 kernel driver there, or to the network layer in general.

    Thanks for the update - we have received a workaround for the bnx2 drives - issues still persist. We have also updated the kernel recently. I have however discovered that the F5 device may be the cause. Currently no new dropped packets so we can't confirm this. Will update as soon as we know.

    Thanks

    Now that I think about it, I had an issue the bnx2 driver on some Fedora/RHEL boxes that was fixed with the
    Code:
    options bnx2 disable_msi=1
    modprobe command. Just throwing that out there...good luck.
