APAR status

  • Closed as program error.

Error description

  • If the DataPower uptime wraps while message counts are being
    monitored for IP's with long delays between logins, SLM can
    trigger when its message count has not actually been reached.
    
    The symptom will be intermittent, obviously incorrect SLM
    triggering, shutting out an IP which has not exceeded its
    message count limit.
    

Local fix

  • A possible workaround is to restart the DataPower appliance
    periodically to reset the Uptime: every 24 days for an XI50 or
    every 49 days for an XI52.
    

Problem summary

  • Affected is the use of count monitors.
    
    Count monitors might get triggered even though
    the actual traffic is coming at a rate significantly below
    the specific rate limit.
    
    This happens when you are trying to sending a series of
    transactions that pass certain points of times (about every 25
    or 50 days, depending on firmware releases). Once
    triggered, all following transactions will be rejected. It will
    not recover without a shutdown reload.
    

Problem conclusion

Temporary fix
