Thanks for the response Scott. We did some firewall reconfiguration with regards to connections and sessions and the issue appears to have gone away.
I've not tried the 3.1 branch in a while as we found it didn't play well with XFire, but I will upgrade to 3.0.25 ASAP. rgds, Richard -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Scott Ferguson Sent: 14 January 2008 16:45 To: General Discussion for the Resin application server Subject: Re: [Resin-interest] Resin clustered session store On Jan 10, 2008, at 4:19 AM, Richard Grantham wrote: > Hi list, > > I'm using Resin Pro 3.0.23 (2 servers, load balanced/distributed > sessions) and I've seen this error a few times in the log file: We've made a few fixes to the synchronization/timing of the clustered session. Some in 3.0.25, but many more in 3.1. However, I was never able to reproduce that exact error here, so if anyone runs into this on 3.1.4 or later, it would be very helpful to send a bug report on the issue with as much detail as possible. -- Scott > > [2008-01-10 11:31:01.379] java.io.EOFException > [2008-01-10 11:31:01.379] at > java.io.ObjectInputStream$PeekInputStream.readFully > (ObjectInputStream.ja > va:2279) > [2008-01-10 11:31:01.379] at > java.io.ObjectInputStream$BlockDataInputStream.readShort > (ObjectInputStre > am.java:2748) > [2008-01-10 11:31:01.379] at > java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:780) > [2008-01-10 11:31:01.379] at > java.io.ObjectInputStream.<init>(ObjectInputStream.java:280) > [2008-01-10 11:31:01.379] at > com.caucho.server.cluster.ClusterObject > $DistributedObjectInputStream.<in > it>(ClusterObject.java:474) > [2008-01-10 11:31:01.379] at > com.caucho.server.cluster.ClusterObject.load(ClusterObject.java:286) > [2008-01-10 11:31:01.379] at > com.caucho.server.cluster.FileBacking.loadSelf(FileBacking.java:318) > [2008-01-10 11:31:01.379] at > com.caucho.server.cluster.ClusterStore.load(ClusterStore.java:423) > [2008-01-10 11:31:01.379] at > com.caucho.server.cluster.ClusterObject.load(ClusterObject.java:259) > [2008-01-10 11:31:01.379] at > com.caucho.server.session.SessionImpl.load(SessionImpl.java:702) > [2008-01-10 11:31:01.379] at > com.caucho.server.session.SessionManager.getSession > (SessionManager.java: > 1278) > [2008-01-10 11:31:01.379] at > com.caucho.server.connection.AbstractHttpRequest.createSession > (AbstractH > ttpRequest.java:1444) > [2008-01-10 11:31:01.379] at > com.caucho.server.connection.AbstractHttpRequest.getSession > (AbstractHttp > Request.java:1256) > [2008-01-10 11:31:01.379] at > com.caucho.server.connection.AbstractHttpResponse.writeHeaders > (AbstractH > ttpResponse.java:1556) > [2008-01-10 11:31:01.379] at > com.caucho.server.connection.ResponseStream.writeHeaders > (ResponseStream. > java:216) > [2008-01-10 11:31:01.379] at > com.caucho.server.connection.ResponseStream.writeNext > (ResponseStream.jav > a:401) > [2008-01-10 11:31:01.379] at > com.caucho.server.connection.ToByteResponseStream.flushByteBuffer > (ToByte > ResponseStream.java:518) > [2008-01-10 11:31:01.379] at > com.caucho.server.connection.ToByteResponseStream.flushBuffer > (ToByteResp > onseStream.java:424) > [2008-01-10 11:31:01.379] at > com.caucho.server.connection.ResponseStream.finish > (ResponseStream.java:6 > 64) > [2008-01-10 11:31:01.379] at > com.caucho.server.connection.ResponseStream.close > (ResponseStream.java:79 > 6) > [2008-01-10 11:31:01.379] at > com.caucho.server.connection.AbstractHttpResponse.finish > (AbstractHttpRes > ponse.java:1956) > [2008-01-10 11:31:01.379] at > com.caucho.server.connection.AbstractHttpResponse.close > (AbstractHttpResp > onse.java:260) > [2008-01-10 11:31:01.379] at > com.caucho.server.webapp.WebAppFilterChain.doFilter > (WebAppFilterChain.ja > va:190) > [2008-01-10 11:31:01.379] at > com.caucho.server.dispatch.ServletInvocation.service > (ServletInvocation.j > ava:229) > [2008-01-10 11:31:01.379] at > com.caucho.server.http.HttpRequest.handleRequest(HttpRequest.java:274) > [2008-01-10 11:31:01.379] at > com.caucho.server.port.TcpConnection.run(TcpConnection.java:511) > [2008-01-10 11:31:01.379] at > com.caucho.util.ThreadPool.runTasks(ThreadPool.java:520) > [2008-01-10 11:31:01.379] at > com.caucho.util.ThreadPool.run(ThreadPool.java:442) > [2008-01-10 11:31:01.379] at java.lang.Thread.run(Thread.java: > 619) > > The servers are configured to persist sessions across the cluster.
