Vertica crash explanation

Hi guys!
Today I have already 4 times when Vertica node goes down.

I'm trying to research what the problem is, but can't found.
My ErrorReport.txt says:

Can someone provide link to manual where I can find some explanations about ErrorReport.txt?

Thanks for help.

  • Hi Dmitriy,

    First, apologies for the crashes!

    ErrorReport.txt is not for end-user consumption; it is intended for debugging by Vertica Support and Engineering.  (It is captured by Support's automated data-collection tools.)

    If you receive an ErrorReport.txt, what that should tell you is that something has gone very wrong with the database...  Usually something that can't be fixed in the field; at best worked around, sometimes fixed by a hotfix, etc.  Not surprising in this context -- you're seeing the database crash of its own accord; that's, of course, something that we work hard to avoid.

    If you have an Enterprise account, please go straight to http://my.vertica.com/ and open a support case.  They have tools to help understand what's going on here.

    If not -- ErrorReport.txt files are often accompanied by a stack trace or core dump.  Could you find and post that stack or core?

    Thanks,
    Adam

    Is there any way to determine what happened for me? Maybe I need to tune my Vertica configuration or create some projections?
     Thanks. And another "Thanks" for your great product, I really enjoy it :)
  • Hello Dmitriy,

    Thanks for your helpful reply with the stack trace.

    It would be helpful to see some additional diagnostic information about your issue. Could you run the diagnostic collection tool for us and point us to the output? The instructions for the diagnostic tools can be found here:

    https://my.vertica.com/docs/7.0.x/HTML/index.htm#Authoring/_IntrabookContent/Links/CollectingDiagnos...

    Thanks!

    Jason
  • Yes sure, but this diagnostic results contain some private information about server, can you, please give your email, I will send it to you?
  • Hi Dmitriy,

    I agree, it is best to follow up off-thread. I will do that right away.

    Jason
