Orphaned rsync process on remote machine?

Upon further investigation, I think I found part of the problem. 
There was a weird circular link in the destination directory.  I'm 
running a test of the fix right now.  I ran a test with no --timeout 
option and that seemed to work.  Then I found and deleted the 
circular link and am re-running with the normal 90-second time out.

What should a "normal" time out be?  Is 90 seconds too long?  Too short?

Thanks,

Marc
