Object
column
SNMPv2-SMICounter32
The number of failures to grant a buffer to a requester due to reasons other than insufficient memory. For example, in systems where there are different execution contexts, it may be too expensive to create new buffers when running in certain contexts. In those cases it may be preferable to fail the request.
