There seems to be an incompatibility issue between utorrent and lattest update of kaspersky internet Security 184.108.40.206 resulting in "Insufficient system resources" errors.
It appears in the "status" of individual torrents making these torrents stop after a while.
Many people are also experiencing graphic/display glitches after KIS has been running for a certain amount of time.
Text and icons are vanishing, fonts become weird and when you want to run a program you get some "impossible to initiate progname" or "progname is not a valid win32 application", etc.
I am not sure if there is any solution found, but I have temporarily disabled the kaspersky firewall.
I wanted to notify all of you,since I am sure others are also having the same symptoms.
