Oddity: rsync *should* be recursing, and dealing with very large number of files. It works, going from box a to box b. But when I try to back b up to c, it fails, 100%, complaining of "out of hashtable space [sender]". I've tried adding -r, and changing --delete to --delete-delay, and no joy.
All boxes are current, or fairly current, CentOS 7.
Anyone got any thoughts on the matter?
