There is a maximum built into every operating system I know, to
prevent an accidental recursive symlink or symlink loop from making
the operating system descend *perpetually* down a directory tree and
get seriously lost. This is similar to the limits on maximum directory
depth, and maximum filename length: we don't notice them until we run
into them, usually due to some other kind of mistake.

Check each component of your path for symlinks. /back, /backup/java,
/backup/java/db, etc., and see which is the problem. You should be
able to replicate the problem by doing "ls -ld" on each relevant
parent directory until one failes.

Such problems are often exacerbated by people doing 'rsync' operations
carelessly and accidentally mirroring symlinks inside of directoryes
pointed to by other symlinks, instead of replacing the symlink. (This
happened to a colleage last week.)
