You can shut down JBoss normally by http'ing to localhost:8082, and choosing the shutdown option. Optionally, you may also kill it by sending the '-INT' signal. i.e. kill -INT pid > Now I suspect that this process is responsible for what's happening. It > seems something like a dead lock.

If you inspect this hung process a little closer (ps auxffww | grep java), you might find that it is not really JBoss, but a 'java -version' process, if you're running Sun's 1.3.x JVM. This did not occur on their 1.2.x JVM, and does not occur on their 1.4.x JVM. It also does not occur on IBM's JVM, or Blackdown's JVM. It's an incompatibility between those version of Sun's JVM and glibc's threading library from what I've been able to ascertain. _______________________________________________ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
