On some occasions, a slave JVM freezes when using stdout/stderr
for communicating with the master. The characteristics of this problem are:
- Only on Windows
- Slave uses its stdout/stderr for communication. This includes launching a slave via command line and via SSH.
- You cannot attach JConsole to the hanging process
- Process Explorer fails to show you the thread list of the hanging process
Adding a debug option to JVM can help with the problem. That is, start JVM like this:
java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=29999 -jar slave.jar
