I'm using s3cmd to sync around 100K files (80gigs) to S3.  Currently I'm running it from within a script that runs hourly to restart the job if it crashes (it checks for a currently running s3cmd process before it starts a new process).  I'm running with the -v option and logging the output.  I see that after around 100-400 files it just craps out and dies with an exit code of 1. 

Any ideas what I should try to resolve this?  I've included my configuration file below and the command line that I use to start it.

I haven't tried running with the --debug feature on large jobs because it generates HUGE logs (over 100megs); if that would be helpful, I can do that. 

command line:
 /usr/local/bin/s3cmd -r -p --delete-removed -v --exclude-from /etc/s3cmd/exclude/etc.exclude -c /etc/s3cmd/s3cfg sync /etc/ s3://<MYBUCKET>/etc/

As I was walkin' - I saw a sign there
And that sign said 'private property'
But on the other side it didn't say nothin!
Now that side was made for you and me!
