Opened: Oct 09, 2018
Severity: 3-Major


On rare occasions, some resources are marked 'unavailable', with a reason of 'big3d: timed out' because gtmd fails to process some probe responses sent by the instance of big3d that is running on the same BIG-IP system.


Some resources are marked 'unavailable' on the affected BIG-IP system, while the other BIG-IP systems in the sync group mark the resource as 'available'.


The monitor response from big3d sent to the gtmd on the same device is being lost. Monitor responses sent to other gtmds are sent without issue. The conditions under which this occurs have not been identified.


Restart gtmd on the affected BIG-IP system.
