There's a good chance the find process you're seeing is being overly zealous. Basically what happens is find, during kiosk session cleanup, takes a heap of time searching through /tmp for any files owned by the kiosk user, trying to delete them in the process. This might include attached USB mounts, resulting in horrible I/O load and network load while it runs through every file on every attached USB stick. I'm pretty sure a more recent version of Sun Ray had a patch in it to fix this.
