看起来您正在运行MQ的V7.1前版本？在MQ V7.1中，错误消息从以下位置更新：-

AMQ9259: Connection timed out from host 'HOST.A'.

EXPLANATION:
A connection from host 'HOST.A' over TCP/IP timed out.
ACTION:
Check to see why data was not received in the expected time. Correct the
problem. Reconnect the channel, or wait for a retrying channel to reconnect
itself.

到

AMQ9259: Connection timed out from host 'HOST.A'.

EXPLANATION:
A connection from host 'HOST.A' over TCP/IP timed out.
ACTION:
The select() [TIMEOUT] 60 seconds call timed out. Check to see why data was
not received in the expected time. Correct the problem. Reconnect the channel,
or wait for a retrying channel to reconnect itself.

作为一个例子。AMQ9259错误消息最可能的原因是您的接收超时设置导致频道弹出其接收并关闭频道。建议您检查qm.ini文件中的接收超时设置，看看它们是否设置得比心跳间隔短。
