I get an error in Bitcoin core that after about 2 hours of user inactivity the program gets shut down by the OS. A dialog window appears "An error has occured and Windows needs to shut this program". I can only click one button and then it proceeds to shut down Bitcoin core (the window is still there).
This happens both in version 0.9.3 and 0.10.rc3.
It even caused a DB corruption once, forcing me to redownload the entire blockchain.
I use Windows XP (SP3) with all patches. I've completely turned off any energy saving/standby modes (only screensaver after 11 minutes which does not affect this).
As long as I am using the computer everything is fine (I use a mouse jiggler program to let it run through).
Does anybody have an idea what the problem could be?
It happened to me using 0.9.3 but when I upgraded to 0.10 it was resolved, Bitcoin Core gets shutdown after few minutes (doesn't matter if I was using the computer or not). I also used a new folder for data (-datadir=...). 0.10 is much faster to redownload the blockchain, it took me less than 4 Hrs.
