QNAP starts but crash out

[Yazsan55]

My friend has QNAP HS210 with loads of music stored.
It has been running with minim 2.1 with no problem. But last couple of days it stops running continuously.
I tried to help him without success. So we decided to update it to 2.2.
It has been successfully installed and it initially starts then starts indexing the library. Then after running a while it crashes out, without being able to access configuration page. HS210 itself is running.

I am wondering the library has some bad file or just too big.

Posting log file will help surely?

Thank you very much for your help.
