Maximum number of client sockets in MicroSocketClientInvoker increases after timeout waiting for a free socket -------------------------------------------------------------------------------------------------------------- Key: JBREM-1305 URL: https://issues.jboss.org/browse/JBREM-1305 Project: JBoss Remoting Issue Type: Bug Security Level: Public(Everyone can see) Components: transport Affects Versions: 2.2.4, 2.5.4.SP3 Environment: all Reporter: Torsten Neise Assignee: Ron Sigal Fix For: 2.2.4.SP1, 2.5.4.SP4 Maximum number of client sockets in MicroSocketClientInvoker increases after timeout waiting for a free socket. This happens because of an illegal call of semaphore.release() in MicroSocketClientInvoker.transport(...) after semaphore.attempt(timeToWait) returned with false (no lock aquired) in MicroSocketClientInvoker.getConnection(...). public class MicroSocketClientInvoker extends RemoteClientInvoker { ... protected Object transport(String sessionID, Object invocation, Map metadata, Marshaller marshaller, UnMarshaller unmarshaller) throws IOException, ConnectionFailedException, ClassNotFoundException { ... try { socketWrapper = getConnection(marshaller, unmarshaller, timeLeft); } ... catch (Exception e) { // if (bailOut) // return null; semaphore.release(); ... } ... } protected SocketWrapper getConnection(Marshaller marshaller, UnMarshaller unmarshaller, int timeAllowed) throws Exception { long start = System.currentTimeMillis(); long timeToWait = (timeAllowed > 0) ? timeAllowed : 30000; boolean timedout = !semaphore.attempt(timeToWait); if (trace) log.trace(this + " obtained semaphore: " + semaphore.permits()); if (timedout) { throw new IllegalStateException("Timeout waiting for a free socket"); } ... } ... }
