Error defragmenting database

We had started with this problem fews days ago.  The wialonb3 service  stop working.
It seems an error in defragmenting database and always shows defragmentation level is 20%.

I am copy part of the log files for the last three days. We had use a script to restart the service automatic, but this problem is producing alot  noise with customs.

Thanks a lot any help about this problem.
