Error description

  • The output of "onstat -g mem" will print a name but this can be
    truncated, which can be an issue when you have many readahead
    entries as you cannot easily match these to the appropriate
    session/thread.

    The readahead entry has a prefix of "RA_req_" followed by a
    thread id and a request id.   On a busy system, the thread id's
    can quickly and easily exceed 9999 and so you see many duplicate
    entries.
