I have a application server for network operations written with Java based on Apache Mina. Recently I encounter a strange behavior in my log files. I noticed that the log file is full of @^@^@^@^@^@^@^@^@^@^@^@^…. characters. I mean those unexpected characters are vast amount of as such the log file gets hundreds of GB in a couple of hours! I have no clue about this problem and it is almost impossible to google it. What could be the reason? Are those set of characters any familiar to anybody?

I can give more details about the application if needed.

Thanks in advance.

    Those characters are null characters (NUL, ASCII value 0) in caret notation.

    In caret notation for control characters the null character is ^@.
