Hello, I have a uima pipeline that uses uima-as 2.3.1 which has one aggregator with one local annotator, one remote consumer and one remote annotator. It actually has more components but I will get into exactly the configuration only if needed. I have developed also a UIMA client for it using class: UimaAsynchronousEngine, method sendCas (async as far I understood) and a callback listener that waits for the processing to complete.
1. I have noticed that the CAS returned, in general is quite big. Is it a way to send, at least to the client, a CAS that does not contain all the types that the various annotators added? When could I remove those things from the CAS? 2. I send a text message for processing which has 48 KB - it gets processed successfully by the pipeline, but the pipeline fails to send a reply to the client. The exception that I get is: 01/21/2014 07:36:02.978 [ActiveMQ Transport: tcp://localhost/127.0.0.1:61616] [DEBUG] org.apache.activemq.ActiveMQConnection - Async exception with no exception listener: java.io.IOException: Frame size of 147 MB larger than max allowed 100 MB java.io.IOException: Frame size of 147 MB larger than max allowed 100 MB at org.apache.activemq.openwire.OpenWireFormat.unmarshal(OpenWireFormat.java:277) ~[activemq-core-5.6.0.jar:5.6.0] at org.apache.activemq.transport.tcp.TcpTransport.readCommand(TcpTransport.java:229) ~[activemq-core-5.6.0.jar:5.6.0] at org.apache.activemq.transport.tcp.TcpTransport.doRun(TcpTransport.java:221) ~[activemq-core-5.6.0.jar:5.6.0] at org.apache.activemq.transport.tcp.TcpTransport.run(TcpTransport.java:204) ~[activemq-core-5.6.0.jar:5.6.0] at java.lang.Thread.run(Thread.java:662) [na:1.6.0_30] 01/21/2014 07:36:03.093 [ActiveMQ Connection Executor: tcp://localhost/127.0.0.1:61616] [DEBUG] org.apache.activemq.transport.tcp.TcpTransport - Stopping transport tcp://localhost/127.0.0.1:61616 As far as I understood, the client connects via JMS to the uima pipeline and a temporary reply queue gets created where the reply from the pipeline should be sent and then consumed by the client. After the above exception is thrown, the connection to the pipeline gets closed and automatically the temp queue gets deleted hence the client does not receive anymore the reply. I am wondering why the error I was mentioning is not thrown while the aggregator sends the CAS to the consumer, because the consumer is remote, hence the communication between them is done through JMS queue as well, and I think the aggregator has a reply queue as well for the consumer... I want to mention that I tried to increase the maxFrameSize on AMQ broker but without success. It seems to be a bug in AMQ 5.6 that uima as 2.3.1 is using. Any feedback is appreciated. Thank you, Mihaela
