I have a multithreaded app that stress test the JBoss version jboss-4.2.2.GA, and i got the following exception intermittened. IS this related to this JIRA ticket: https://jira.jboss.org/jira/browse/JBAS-1380? ERROR [STDERR] org.jboss.mq.SpyJMSException: Cannot authenticate user; - nested throwable: (java.net.SocketException: Connection reset) | 2008-12-24 00:03:22,984 ERROR [STDERR] at org.jboss.mq.SpyJMSException.getAsJMSException(SpyJMSException.java:72) | ... | ERROR [STDERR] Caused by: java.net.SocketException: Connection reset | 2008-12-24 00:03:40,703 ERROR [STDERR] at java.net.SocketInputStream.read(SocketInputStream.java:168) else what could be the root cause?
