    Hi,

     

    Please share the contents of <catalog directory>/ErrorReport.txt  from this node - this may include a backtrace that will provide more information re why Vertica process went down with a PANIC.

     

    Thanks

    Hi 

     

    If you have support license I would suggest you to raise a ticket with Vertica support for the same to get proper information if you have hit a known bug and Support can help you avoid the occurance of such issue from happening in near future.

     

    Thanks

    Rahul
