......@@ -53,6 +53,22 @@ The asynchronous I/O code encountered an error when trying to send data to
the specified address on the given protocol. The number of the system
error that caused the problem is given in the message.
% ASIODNS_UDP_ASYNC_SEND_FAIL Error sending UDP packet to %1: %2
The low-level ASIO library reported an error when trying to send a UDP
packet in asynchronous UDP mode. This can be any error reported by
send_to(), and can indicate problems such as too high a load on the network,
or a problem in the underlying library or system.
This packet is dropped and will not be sent, but service should resume
normally.
If you see a single occurrence of this message, it probably does not
indicate any significant problem, but if it is logged often, it is probably
a good idea to inspect your network traffic.
% ASIODNS_UDP_SYNC_SEND_FAIL Error sending UDP packet to %1: %2
The low-level ASIO library reported an error when trying to send a UDP
packet in synchronous UDP mode. See ASIODNS_UDP_ASYNC_SEND_FAIL for
more information.
% ASIODNS_UNKNOWN_ORIGIN unknown origin for ASIO error code %1 (protocol: %2, address %3)
An internal consistency check on the origin of a message from the
asynchronous I/O module failed. This may indicate an internal error;
