APAR status

  • Closed as program error.

Error description

  • Load Balancer for IPv4 and IPv6 for AIX sends HA packet every 1
    second. We expected the HA packet should be sent every 0.5
    second.  With the default hatimeout value, 2 seconds, it might
    have a risk for the unexpected failover to be occurred.
    

Local fix

  • Increase hatimeout value to mitigate a risk of unexpected
    failover.

Problem conclusion

  • The problem occurred because HA timer was set to expire for
    every 1 second. Now it is set for every .5 second timeout.
    This fix will be available in FP version 8.5.5.9, 8.0.0.12 and
    7.0.0.41
