Error description

  • When an incorrectly huge memory pool is asked, DB2 attempts to
    create it rather than returning an error. This can lead to an
    exhaustion in the memory resource in the box.
    This problem occurs only in a rare event, where the DB2
    component needing a memory pool incorrectly calculates the
    amount they need. So far, the only known such scenario is when
    runstats was run with quantiles and freqvalues values more than
    twenty thousand.
    n/a
    n/a
    

Local fix

  • Refrain from running runstats with very high freqvalues and
    quantiles.
