There are two problems here: 1. When walking the directory structure, rsync keeps all directories above open. When the current process' max number of files is reached, the party is over. Suggestion: wrap opendir and have it read the entire directory at once. 2. The directory is being walked without ckdir-ing into subdirectories. That's a severe performance penalty for deep directories. Alternatively, at least on Solaris, use fstatat(2) for stat-ing the files.
