Luks partition busy although it is dismounted

I have a luks partition that gets "locked" frequently, although it is unmounted. Like this:

sudo cryptsetup luksClose /dev/mapper/cryptstore
Device /dev/mapper/cryptstore is busy.

Reboot solves the issue, but I dont want to reboot evereytime I close this partition.
sudo lsof /dev/mapper/cryptstore gives no output. The version is cryptsetup 1.2.0-1.

Here is the stat output

sudo stat cryptstore
  File: `cryptstore' -> `../dm-5'
