I thought about that, but as I read the report at least, number of 
connections at once shouldn't have anything to do with the problem.

Because if it was number of connections, pan might only download three 
things at once, but as they finished with the first downloads they'd 
continue with additional downloads in the queue as expected.

Either that or if the connections were somehow going stale, due to too 
many dropped packets say, manually telling pan to download more after the 
first set had finished wouldn't do anything either, as the existing 
connections would still be stuck, and it does, so it doesn't appear to be 
existing connections going stale and a limit of four connections 
preventing new connections from being established.

So I don't see how it could be related to pan's default limit of four 
connections per server.  The symptoms simply don't fit that scenario, 
unless there's an additional piece to the puzzle like the weird server 
behavior and/or possibly logged errors I suggested.
