the messages seem to still be in the system (so not gone, which good :-) ). after restarting one of the message producers all of the "missing" messages started at once appearing in the queue as expected. is there a known issue with long-running producers?

This has been working fine for a while but then we have noticed that the rates (each step of the processing workflow delivers stats) do not add up. namely we seem to be losing messages (around 200 messages/sec) and this is quite discerning. The reason is that these messages do not show up in the queue and are also not visible as being recieved and un-acked. we are using non-durable queues and a combination of java and python processing clients.
