Both machines are running Ubuntu 12.04

Remote NFSv4 Client

$ ls /mnt/storage/aaaaaaa_aaa/bbbb/cccc_ccccc gives this error:
ls: reading directory .: Too many levels of symbolic links

How can I fix this?

When error occurs ls start listing the files, however PHP brakes.

On the NFSv4 Server

In /etc/fstab:

/mnt/storage    /srv/storage    none    bind    0 0

In /etc/exports

/srv         192.168.1.0/24(rw,async,insecure,no_subtree_check,crossmnt,fsid=0,no_root_squash)
/srv/storage   192.168.1.0/24(rw,async,nohide,insecure,no_subtree_check,no_root_squash)

I came across it in PHP. scandir would return 1612577.gz & 1612579.gz, but skips 1612578.gz and yet the file types and properties are identical on them

and this only happens on the nfs client, works 100% on the server
