Darkcoin daemon shuts down, any idea?

Around 5 minutes after I log out of my SSH session my daemon seems to shut down and I have no idea why. This is the tail of the debug.log:

Looks like a permission error. But why does that only happen after I log out? Any ideas?

Definitively insufficient write permissions on .darkcoin/leveldb directory - deferred occurance IHMO not related to logout, but new block arrival (blocktime ~2.5min)

But, but, ... this does not happen as long as I'm logged in. This is how it looks like when I'm logged in:

Hmm, voodoo?
 
What account is the from in running under? Is it your account? If so, try making a new account and running the service under that account
 
How are you starting the daemon?

Try
Code: 
./darkcoind & disown
and see what happens.

I run it in daemon mode already.
Code: 
darkcoin -daemon

It might be caused due to encrypted home directory.

You need to be starting the daemon in a screen session.

apt-get install screen
login as the user who's going to run darkcoind
screen /bin/bash (to start the screen)
darkcoind (assuming darkcoind is in your $PATH)
ctrl a+d (to detach from the running screen)

Hello ?
I see that that error is in the file db.cpp, CAddrDB::Write(..) where a temporary, empty version of peers.dat is created. That seems to be failing, though I can't see how the CAddrDB::CAddrDB(...) constructor can tell that
Code: 
file
is NULL??

You would have to run long enough for the peers.dat to be rewritten again, to see if it happens then too. The peers.dat file is in the "datadir" directory, traditionally where the wallet.dat and error files are located.

As was stated, check your program's permissions in/on this directory (are you running Windows vista, 7 or 8?)

I compile bitcoin and a few other alternate crypto-currencies using MSVS, so that I can debug in the full IDE. That would show me what is going on. I'm running darkcoind.exe 0.9.11.6, gcc compiled on Windows and I don't see that problem, while running or exiting.
