Description
Cause Suggested Resolution
Bacnet IP DLL
Temporarily out of
receive buffers
The FieldServer was flooded with more BACnet IP packets
than it could handle. This typically occurs when a
workstation discovers a large network resulting in many
Who-Is and I-Am broadcasts. The FieldServer will recover
from this, but some timeout errors could result. Take action only if the error
is continuous in which case
the network load must be
analyzed and corrected.
