These are broker logs, or client logs? Whichever it is, what's in the other process's logs at the same time?
You said that reconnecting isn't possible for hours after this happens. Do you see the same messages in the logs for that whole time? At the time this happens, what are the client(s) and the broker doing? Can you reproduce the problem reliably in a minimal setup (just one or two clients, minimal time and message load)?
