yeah you can set thread to 1024 and i scans but doesn't stop as i said crashes
when stoping that's because of the limit 
for seeing the limit
open terminal 
adn type : wine /root/Desktop//../kportscan.exe(app location)
and give it a large range (having at leat 10000 ips)
now look at the terminal you see wine sayes in terminal : "wine client
error:41c: pipe: Too many open files"
if you set the thread more than 580
nad when you see this te app freezes when stoping
it doesn't matter tat it freezes at stooping or going to nest line range ( if
the problem was only this app i would use another app i've tested a few apps
and it appens)
what matters is that you can't have more than 580 tcp connection at the same
time with one proccess in wine

i open two kportscanners at two diffrenet folder and gave than 400 treads each
and i saw that it worked perfectly 
so the problem can't be "linux core limits the max tcp thread to 580"
guy do you have any linux based app so you can test these apps and see if the
problem exits if exist than the problem is from linux core not wine

thanks for helping
