error while parsing /proc/net/unix (psutil 3.2.0) #766

Closed teto closed 8 years ago

giampaolo commented 8 years ago

Can you try with latest GIT version?

teto commented 8 years ago

Installed with python3.4 -mpip install -U https://github.com/giampaolo/psutil/archive/master.zip and doesn't seem to fix it, should it ?

teto commented 8 years ago

thanks ! I can't really confirm if the fix works since it depends on what I launch on my machine I guess but in the contrary you will see me again :)
