Download of a file stalls after short time, but when I switch "A4AF"-files it continues (and then stalls again); behaviour can be iterated.

[dreirund]

I have a strange issue both with amule-dlp and also with amule (official non--dlp variant) that many downloads start off with good download, then suddenly stop.

When I select another file that isn't currently downloading because the uploader was asked by my client for another file (this behaviour called "A4AF"), more precicesly the file I mentioned above that stopped downloading, and then "Swap every A4AF to this [other] file now", then the new file get's downloaded for a short time (a few tens of seconfs or minutes) and then stalls, too.

I repeadedly can play this game to get downloads going, but it needs manual intervention.

Automatically, eventually some download will continue, but it takes very long, and I am not sure if it only continues after the sources are gone for a short time and reappear.

I have no idea what can be the reason for this or how to track this down and if this is some sort of issue/ bug or intended behaviour of ed2k.

Regards!
