It’s very rare our application ends up with messages in the Failed group, and they tend to replay fine. However, we have a batch process that occasionally leaves us with hundreds of messages in the failed group. Sometimes when we retry either one or two or the whole group, the messages often end up in ‘send messages to retry… (Queued)’ for a long time (maybe an hour) - and we’ve currently got a batch that are stuck after almost a day.
I’m fairly new to NServiceBus and this architecture - is there a way to find out why these messages are pending, or to help shuffle them along?
FWIW, we’re using NServiceBus 5.2, and using ServiceControl 1.42.0 - we plan to upgrade but it has not happened yet.
