Geofferic's your problem is not related to Trashguard's problem and I never saw anything like this... Can you tell me more about your configuration.
How long does it take till the downloads stop working?
Which operation system are you using?



Trashguards problem is related to the number of parallel active download connections. They are limited! and if you get queued each queue uses one download connection. This is protocol related. Once all parallel connections (for either a single file or total) are used up with queues there are no more free connections.
All you can do is to raise the number of parallel connection if you system is able to handle it. Queued downloads use very little bandwidth but they hold a open network connection.
