When I try setting up a queue sender that sends 5120 byte messages I get the following exception: Exception in thread "CompileThread0" java.lang.OutOfMemoryError: requested 65544 bytes Possible causes: - not enough swap space left, or - kernel parameter MAXDSIZ is very small. java.lang.OutOfMemoryError: at java.util.zip.Deflater.init(Native Method) at java.util.zip.Deflater.

SwiftMQ uses message body compression by default. The threshold is 2 KB. As you see, 64 KB are requested during compression and your client runs out of memory. Give it more heap size, e.g. -mx256M. You can also switch the compression off by setting the resp. message property:


msg.setBooleanProperty("JMS_SWIFTMQ_BC",false);
