Affected Product:  See more info
BIG-IQ Platform(all modules)

Known Affected Versions:
4.6.0, 5.0.0

Fixed In:

Opened: Jun 28, 2016
Severity: 3-Major


When a BIG-IP is discovered and monitored from the BIG-IQ, it may occasionally be marked as down for one minute.


Very rarely the discovered BIG-IP will be marked down for one minute, even though it is up. If customer has an alert configured, it will alert the customer that the BIG-IP is down.


BIG-IP is discovered and actually up. The more BIG-IPs that are discovered, the more likely this issue is to be seen in a given time period.


There is no known workaround.

Fix Information

We corrected a timing issue with connections between BIG-IQ and managed devices to resolve the possibility of inaccurately reporting managed BIG-IP systems as down.
