I upgraded wine to Debian unstable's version as of two weeks ago, I think it was 0.9.51 or 0.9.52. Unfortunately for some reason it didn't seem as stable as the one I was using before that. Servers were starting, but after some time (in the amount of hours, I think) they stopped by themselves without anything informative in the log file.
Then again, it's perhaps the strange way by which I'm starting them up. (I use screen, wineconsole --backend=curses, Start Windowed 0, /dedicated=invisible).
In any case, I've reverted to my favorite stable version: 0.9.34-1 (Debian Unstable). This has been running great and with no problems at all, with uptime of MONTHS for me!
