    hello guys, this is my first time here as a registered user.
    first of all, i wanna say sorry about my english, i talk spanish.
    i come with a big problem..
    the thing is:
    i buy a vps from volumedrive at is the package 2.
    i follow this tutorial and everything goes well.
    two days ago volumedrive suspend this vps because process named was causing high resource usage.
    after a long day they give me a new vps because the old one was "rare". none of us was able to make an os-reload in this vps didn't know why...
    anyway i ask volumedrive about resource limitations and they told me this:

    If the VPS causes such an issue that other VPS on the node are affected we cannot wait for a response from you. The load average limit is 5. Anything above that it gets suspended. You need to monitor your own VPS.

    two things: 1°, what means 5 and how to monitor this? and 2°, what can i do whit bind to decrease resource usage?

    i have read this articles and seems to work for these users:
    can you guys tell me some "solution" for this?
    if i use mydns instead bind i will se same error ¿?
    i was a w2k user sense 1° time, but now in linux im in troubles :)
    thanks in advance.

    pd: one of the first support ticket i send when vps was suspended they answered this:

    your VPS was suspended for causing the node to spike to a 17 load average.
    process causing it:

    [[email protected] ~]# vzpid 623402
    Pid CTID Name
    623402 373 named

    i will update this post after i check your solution.
    in a few words it's recomended turn off recursion right?

    Yes. Otherwise your server might be misused for dns based dos attacks which might explain the high dns usage.

    ok, if i put:
    allow-transfer {“none”;};
    allow-recursion {“none”;};
    recursion no;
    in resolv.conf.options bind doesn't start.
    and shows: Recursive resolver is not detected on with or without modifications in resolv.conf.options
    so, in this case openresolver seems to not work.
    if i put just: recursion no; bind start ok.

    my scenario is:
    debian wheeze x64
    the perfect server with ispconfig3
    all apdated & upgraded.
    3 sites in the server working ok.
