Resource Monitor Worker xxx appears to be non-yielding

  • I am seeing this error in the sql error log and we seem to be having a 'slow down'

    'Resource Monitor Worker xxx appears to be non-yielding on node 0.Memory freed 59048kb. Last Wai:MISCELLANEOUS.Last clerk type CACHESTORE_OBJCP,name Object Plans. Approx CPU:Used:kernel 0ms, user 0ms, interval 4638609 '

    What exactly is this error ?

    There is also a mini dump file generated yesterday in the sql log folder. How do you open these files to read what is in them ?

    I have googled this and people who manged to open the dump file also had messages about sql server paging out to disc so I wondering if this info will be contained within the dump file.

    Thanks

  • Sounds like you're hitting this issue. Are you sure this is a SQL SErver 2012 instance?
