After running a Windows guest for about two weeks the machine lost its network connection (port forwarding didn't work). I tried to save the state of the machine and I got ''too many open files'' error and the machine got stuck. I had to kill the machine and start it again. Log is attached. I have noticed that the VirtualBox process opens /dev/zero many many times, which might be the cause since the number of open instances slowly increases over time. {{{ # lsof | grep ""VirtualBo"" |grep ""/dev/zero"" | wc -l 3913 }}} I believe this might be related to ticket #6464, however in this case the error appeared over time by itself.",defect,closed,host support,VirtualBox 4.0.4,fixed,,,Windows,Linux
