It's confirmed guys... even curl connections with S3 does this... so
basically, when I download
230-234 items from S3 or FTP, the curl issues show up, e.g. saying that curl
can't connect to
the server.
I'll forward this problem to libcurl, and hope you guys could also help me
out. This could be a
Mac-only problem.
