Extracted from IRC chat with cposta: I'm getting "IOException: Could not post command" using the http transport on AMQ 5.7. Any tips on what I should be looking at to fix this? This is going to be a low volume, but possibly large message size, server.
I'm sending in a TextMessage with text set to a string created from an empty byte array, just so I can experiment with sizes. 10mb fails, 5mb completes ususally, just ran a 6mb and it completed, 7mb failed with same error We are going to be pretty low volume, maybe 500-600 messages a day, but the payloads can be larger heap size is 1024mb Client Trace: javax.jms.JMSException: Could not post
