I need your help

With differents clients, differents o.s. ( XP & W7 Enterprise - RAM=4GB) and differents HDS PRO versions I have problems with the function in object.
Actions:
Configuration --> Update tab --> Backup configuration
In the right window, when I press “Salva” (Save):
- sometimes HDS self closed and self restart with these intems in the log.txt

20/11/2015 12.30.42.338 CLOSING 4.60.13 PRO HTTP:0, TCP:0
- sometimes nothing happens
- sometimes the configuration is correctly saved
If you have a bit free time, pls check if on your systems run all fine
Thanks very much for you collaboration!!
