http://issues.apache.org/bugzilla/show_bug.cgi?id=41214 ------- Additional Comments From [EMAIL PROTECTED] 2007-01-30 10:56 ------- I'm very confused about what could be causing this, but here's some more information that I have: * We run the same code with the same JVM version on Linux 2.6, Solaris (Sparc/x86), and Windows. * We see these problems only on Solaris machines (Sparc and x86). * We have hundreds of unit tests, and they all using logging a lot. In several consecutive runs, the exact same logging statement as described in Additional Comment #14 caused the deadlock, not any other of the thousands of logging statements. * I see one other case during this test run of a deadlock, which is described below. * Ocassionally I will see a similar deadlock in a completely different piece of code that has nothing to do with log4j. A thread will be sitting in Object.wait(), when I know it must have had Object.notify() delivered to it. I have never seen this happen with the same unit test on Linux/Windows. This unit test runs many times a day on all our platforms. This makes me think this problem is a very rare bug in Solaris JVM or Solaris itself, that is triggered by a specific sequence of events in our code. Although that seems unlikely... Here's another instance of our "deadlock": at org.apache.log4j.helpers.CountingQuietWriter.write(CountingQuietWriter.java:45) at org.apache.log4j.WriterAppender.subAppend(WriterAppender.java:301) at org.apache.log4j.RollingFileAppender.subAppend(RollingFileAppender.java:236) at org.apache.log4j.WriterAppender.append(WriterAppender.java:159) at org.apache.log4j.AppenderSkeleton.doAppend(AppenderSkeleton.java:230) at org.apache.log4j.helpers.AppenderAttachableImpl.appendLoopOnAppenders (AppenderAttachableImpl.java:65) at org.apache.log4j.Category.callAppenders(Category.java:203) at org.apache.log4j.Category.forcedLog(Category.java:388) at org.apache.log4j.Category.log(Category.java:835) at com.scalent.shared.util.Logger.log(Logger.java:352) -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
