Re: java.lang.OutOfMemoryError: allocLargeObjectOrArray

Well, if there were no change at all, the behavior won't change at all. Since you did not change the SwiftMQ Router configuration etc, it is very likely the memory consumption is caused by your JMS clients. To get an OOM it is enough if the is a single huge message sent into the system. I therefore recommend to reduce the consumer cache size. Keep in mind this effects throughput so you shouldn't set it to one but to 50 and if that doesn't work to 10.
