Yeah, I'd recommend against using the dump option for that purpose.

What you observe is a combination of several issues:
* First, the recorded source goes temporarily down, which cause the file output to restart
* Second, the file name's variable are too restricted and lead to a new file opened after each restart

There are several things you may do to mitigate the situation:
* Have a less restricted filename, for instance only down to the hour and use the append option to make sure the new stream is added when the source restarts
* Find a way to make sure that the dumped source never goes down. You can use for instance a mksafe for that. However, if you go this route then you'll have to think about a way to make sure that the archive actually stops.

All this being said, I think I'd start by looking at why the source goes down. If that's a live source, it certainly indicates a gap in the audio data, which should not happen, regardless of the issue with dumping an archive of it..

Good uck!
