Strange errors with userman

I have strange errors related to userman …
Im using ROS 6.9 on x86 .
What is hapening ?

  1. Im using 2 logins (shared) for same profile like is discribed in this post http://forum.mikrotik.com/t/usermanager-hotspot-shared-users/34732/1
  2. Status page is setup to show remaining time or remaining transfer limit (depend of user profile) , this is discribed in this post : http://forum.mikrotik.com/t/routeros-hotspot-status-page-variables/29433/1

After some time 18-24 hours this 2 things is stop to work …
1.Userman is don allow second user to login …
2.Status page start to show wrong values - user with transfer limit - show time limit…

Everythig start to work normal after reboot - for now I have schedule system reboot in the morning hours , but sometimes it will not - so then I must do again manualy reboot.
It is very problematic to do reboot when users are online , so I need help.

I have 2 hard disc and I was activate userman to my sata disc … like in picture

(Im suspicious to errors on hard disc) , but without change … same again - must be reboot to work again.
Every idea is welcome …
