I use wcs mod on python for linux server v64, slots 40+ and my server crash every 30-45 min.
What working stability?wcs or w3s?

you're doing something WAY wrong.

not entirely sure what, cause now-a-days wcs shouldn't be doing that.  is it a newer version of wcs, because i know that eventscripts used to screw it over, but ES broke with OB update.

regardless, you should probably use war3.  you can make it pretty much identical to wcs if you actually put some time into configuring the races and making some changes to the core.

thanks all
