Nobody process in LS 4.2.2
Was eager to remove Etags from header, so I quickly requested my server admin to update LiteSpeed to version 4.2.2.
Shortly after that I noticed that I couldn't upload images from Wordpress.
After reporting this problem to my server admin, he checked and found that litespeed is running some php processes as user "nobody" while some under the proper user.
Downgraded back to the previous version and the problem went away.
