Re: hadd: "too many open files"

On UNIX-derived systems (e.g. Mac and Linux), the ulimit command can increase the limit on the number of open files, up to some system-defined maximum. It is an internal shell command, and applies to all commands run from that shell. On my Mac, the default limit is 256, and the maximum I can set it to is 1024.
