--- Comment #1 from Ken Sharp kennybobs@o2.co.uk 2012-10-02 02:27:48 CDT --- The man pages claims ulimit(1) is deprecated but it works fine here.
With ulimit -c 0 the wineserver reports in the console that it has crashed.
With ulimit -c unlimited the wineserver simply disappears.
No idea how I can debug this further.
An strace or +wineserver will be enormous as it takes a while for this bug to appear, and is dependent on the number of jobs available to process.
