行为异常-控制台停止打印

Question

I have encountered some strange behavior which I can't explain.

I'm using boost log v1 to log to the console using wtext_ostream_backend and to a file using wtext_file_backend .

Everything usually work fine, but just the other day the application stopped printing to the console, though it continued to log to file. When I looked in the file for the line where the console stopped printing i noted something strange:

0: [02/07/12 13:49:38] [07437538] [info]    Client 10.28.62.1 was disconnected
1: [02/07/12 13:49:40] [07437538] [info]    Received message from 10.50.128.77: [02/07/12 13:49:40] [07437538] [info]    Sent message to 10.50.128.77: 400 ERROR\r\n2[02/07/12 13:49:40] [07437538] [info]    Received message from 10.28.48.9: VERSION\r\n
4: [02/07/12 13:49:40] [07437538] [info]    Received message from 10.28.48.9: VERSION\r\n
3: [02/07/12 13:49:40] [00C79D10] [debug]   Executed command: VersionCommand

If you look at line 1: you can see that Received message from 10.50.118.77: abruptly end and the next message is written without line breaks. Which otherwise never is the case.

The last thing the console printed was Received message from 10.50.118.77: .

Any ideas what might cause this? Could it be some weird character that followed Received message from 10.50.118.77: that messes everything up? How can avoid/tolerate such characters?

也许您没有正确地使用null char终止字符串。
