Ok although the unit test pass, but with manual test I sometimes got OOM
still. Look at this code in ChannelImpl.send():
resendCache.add(packet);
https://github.com/clebertsuconic/activemq-6/blob/new-Bridge/activemq-core-client/src/main/java/org/apache/activemq/core/protocol/core/impl/ChannelImpl.java#L294
When sending a large, each packet holds a chunk of it, and because it's
stored in the resendCache, it doesn't get gc'ed after the bytes are sent to the
other node. Eventually before the large send complete, all previous sent chunks
will be held in memory.
any comment?
