Centos – Transmission-daemon service spontaneously stops

I've installed, configured and ran transmission-daemon on my CentOS 6 machine using

service transmission-daemon start

This works nicely, and I can see the web interface on http://server.ip:9091 as I need to. The problem is, that several minutes later, it spontaneously stops. Never says anything, without warning or error message.

This happens even when I have no torrents active at all (as in, none on the list).

I have no idea what's wrong, and the error logs I thought of (which probably isn't much) show nothing.

How can I diagnose the causes for this? Has anyone else experienced a similar problem?

EDIT

After the suggestion Martin gave me, I got the log. It goes like this:
[03:07:02.182] Transmission 2.13 (11501) started (session.c:624)

[03:07:24.189] DHT Attempting bootstrap from dht.transmissionbt.com (tr-dht.c:241)

It hangs on that last one until it dies. Now I've looked into this question, but my settings file is already owned by transmission, and even changing the permissions on the file to 775 didn't seem to have any effects.

Any ideas?
