Hi Andy, The following code as replacement of the Snmp.close() method should fix the problem:
public void close() throws IOException { for (Iterator it = messageDispatcher.getTransportMappings().iterator(); it.hasNext(); ) { TransportMapping tm = (TransportMapping) it.next(); if (tm.isListening()) { tm.close(); } } CommonTimer t = timer; timer = null; if (t != null) { t.cancel(); } // close all notification listeners if (notificationDispatcher != null) { notificationDispatcher.closeAll(); } List pr; synchronized (pendingRequests) { pr = new ArrayList(pendingRequests.values()); } for (Iterator it = pr.iterator(); it.hasNext(); ) { PendingRequest pending = (PendingRequest) it.next(); ResponseEvent e = new ResponseEvent(this, null, pending.pdu, null, pending.userObject, new InterruptedException( "Snmp session has been closed")); ResponseListener l = pending.listener; if (l != null) { l.onResponse(e); } } } Best regards, Frank On 03.03.2010 11:33, Andreas Kessler wrote: > Hi all > > I use the snmp4j in JBoss, I created a resource adapter (JCA) who get > used by several threads.
