Error: "write size larger than buffer can fit" when opening object in workbench ------------------------------------------------------------------------------- Key: DROOLS-3552 URL: https://issues.jboss.org/browse/DROOLS-3552 Project: Drools Issue Type: Bug Components: DSLs Editor Affects Versions: 6.5.0.Final Environment: KIE Drools Workbench - Distribution Wars-Version: 6.5.0.Final Server version: Apache Tomcat/7.0.76 Server number: 7.0.76.0 OS Name: Linux OS Version: 3.10.0-957.1.3.el7.x86_64 Architecture: amd64 JVM Version: 1.7.0_161-b13 JVM Vendor: Oracle Corporation H2 database Reporter: Petr Farmakovsky Assignee: Michael Anstis Priority: Major Attachments: Error.jpg, Error2.json To reproduce the error, I created a new repository, created a 300 Data Object in it. In each Data Object created 1000 fields of type Integer. After restarting the server when opening any object, Drools Workbeanch writes an error: *write size larger than buffer can fit* {noformat} java.lang.RuntimeException: failed to enqueue message for delivery at org.jboss.errai.bus.server.ServerMessageBusImpl.enqueueForDelivery(ServerMessageBusImpl.java:443) at org.jboss.errai.bus.server.ServerMessageBusImpl.send(ServerMessageBusImpl.java:391) at org.jboss.errai.bus.server.ServerMessageBusImpl.send(ServerMessageBusImpl.java:337) at org.jboss.errai.bus.server.service.MessageBusProxy.send(MessageBusProxy.java:87) at org.jboss.errai.bus.client.api.base.ConversationMessageWrapper.sendNowWith(ConversationMessageWrapper.java:238) at org.jboss.errai.bus.client.api.base.DefaultMessageBuilder$1.sendNowWith(DefaultMessageBuilder.java:84) at org.jboss.errai.bus.server.io.ValueReplyRPCEndpointCallback.callback(ValueReplyRPCEndpointCallback.java:22) at org.jboss.errai.bus.server.io.RemoteServiceCallback.callback(RemoteServiceCallback.java:54) at org.jboss.errai.cdi.server.CDIExtensionPoints$2.callback(CDIExtensionPoints.java:396) .. {noformat} The full text of the error is attached in the file. I know about the description https://developer.jboss.org/thread/220428 but I did not find the parameters under which you can open objects. I found an error in the TransmissionBuffer.java class, but I don’t know how to fix the problem.
