Hello Michael, It's either a very serious bug in logback, or there is something else going on, such as another process writing to the same file. Could you please enter a bug report describing the problem? Mark the bug as critical. Is the duplication occurring in ConsoleAppener or in RollingFileAppender? Which version of logback is this? TIA, Michael Olson wrote:
Hello all,
I'm new to logback, and I'm trying out a configuration that is, more or less, a word-for-word transcription of an example configuration from the documentation; you can view the configuration here: http://logback.pastebin.com/m1a6f2875
I'm having problems where I'm getting interleaved messages on a single line. I don't believe this is expected behavior, and it certainly makes it harder to understand what's going on. I've tried searching the mailing list and bug list to no avail. Here's an example from one log file: 2009-09-30 15:45:31,649 [Thread-5] INFO CalaisSubmitter - CalaisFeedSubmitter clean shutdown 2009-09-30 15:45:33,2302009-09-30 15:45:33,230 [ [Thread-15] INFO PostItemSubmitter - Shutdown aborted queue operation Thread-19] INFO PostItemSubmitter - Shutdown aborted queue operation 2009-09-30 15:45:33,231 [2009-09-30 15:45:33,231Thread-17] [ INFO PostItemSubmitter - Shutdown aborted queue operation 2009-09-30 15:45:33,231 [2009-09-30 15:45:33,231Thread-17] [Thread-21] INFO PostItemSubmitter - Shutdown aborted queue operation 2009-09-30 15:45:34,230 [main] INFO Eventweb - All stopped
and here's an example from another log file: 2009-09-30 15:47:10,061 [Thread-5] INFO CalaisSubmitter - CalaisFeedSubmitter clean shutdown 2009-09-30 15:47:11,3782009-09-30 15:47:11,378 [ [2009-09-30 15:47:11,378 [Thread-15] INFO PostItemSubmitter - Shutdown aborted queue operation 2009-09-30 15:47:11,3782009-09-30 15:47:11,378 [ [2009-09-30 15:47:11,378 [Thread-15]Thread-21]Thread-17] INFO PostItemSubmitter - Shutdown aborted queue operation 2009-09-30 15:47:11,3782009-09-30 15:47:11,378 [ [2009-09-30 15:47:11,378 [Thread-15]Thread-21] INFO PostItemSubmitter - Shutdown aborted queue operation 2009-09-30 15:47:11,378 [Thread-19] INFO PostItemSubmitter - Shutdown aborted queue operation 2009-09-30 15:47:12,378 [main] INFO Eventweb - All stopped
Can anyone tell me why I'm getting interleaved messages, and what I might be able to do to prevent this from happening?
Thanks, - Michael
