<05/03/14@22:45:24> [source] no data (30s timeout). disconnecting.

This, right here, is your problem. And it appears to be happening pretty often.
It means that your source is constantly disconnecting for some reason. It's usually a network problem.

Their network seems to be ok.  Got this error today in the logs.

It seems like they are doing something weird.
