Hi,
I have some strange problem. I've discovered that my node of version 13.3 kept litecoin log from 2013-08-21 (when I've installed it) to 2013-08-22. No log since 2013-08-23; yesterday it have stopped payment to default address for found shares. I've restarted it, and now I see log for 2013-12-04.
Why this can happen?
If your hard drive was full or some other error happened while writing to the log file, it just stops writing to the log file but continues to work.
