Symptoms

The big3d process may leak memory. As a result of this issue, you may encounter one or more of the following symptoms: You notice a progressive increase in the amount of memory that the big3d process uses. The big3d process produces a core file in the /shared/core directory. The BIG-IP system unexpectedly fails over to another system in the device group. The monitoring system marks the monitored device as unavailable.

Impact

Memory usage for the big3d process increases, and may eventually affect other services and overall system performance.

Conditions

This issue occurs when all of the following conditions are met: Your system is actively monitored by a BIG-IP GTM or Enterprise Manager system. The monitoring system is configured with discovery enabled. The big3d process returns error messages to monitor requests.

Workaround

None.
