Linked server query suspended on ASYNC_NETWORK_IO

  • I have a linked server query that has been suspended for the last 5 hrs on ASYNC_NETWORK_IO.

    The funny thing is that the linked server is between 2 instances on the same machine!

    I didn't think network IO would be an issue in this case.

    Can someone please shed some light as to why there would be a network bottleneck in a linked-server query connecting 2 instances on the same machine?

  • Hello,

    Does this problem happen every time or is it just a one of?

    If it has just happened once then may be check the account under which you are linking e.g. is it locked out, has the password changed, have permissions been changed on either server.

    If it is repeatable then may be look at this thread: http://www.informit.com/articles/article.aspx?p=686168&seqNum=5
