@ -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;
