ReadyNAS 104 - SMB Shares randomly disconnect from OS X Yose

Interesting.
While I got kicked off the NAS earlier on my iMac, I notice another Mac here running 10.10.1, which I mounted one of the NAS shares after performing the NAS update, did not disconnect this time and is still mounted.

NAS System Log shows when I mounted it:

Jan 14 08:15:00 STUDIO_NAS smbd[1922]: pam_unix(samba:session): session opened for user Studio by (uid=0)

EDIT:
This share did eventually get disconnected though:
