[ replying to the list, forgot to earlier ]

This error can safely be ignored, though it can indicate that the
peer is not responding or GRE packets are otherwise unable to get
through.

An "occasional" occurrence of this error is normal. It indicates
that the GRE transmit window is full (i.e., still waiting for
acknowlegements to be received from the peer for previously
transmitted packets).
