Hi list, I have a few mount points to Microsoft Windows 2000 SP4 and a simple process that repeatedly opens files by name, reads the first 256 bytes and then closes it. Yesterday I was testing some unrelated applications in face of network problems and I used tc/netem/mirred/ifb to cause 50% packet loss on the receiving side. Shortly after setting it up, CIFS started reporting various errors from the mount point, though I was not aware of that. Today, I was updating my system using pacman and it hung because it does statvfs on every file system to find the amount of free space. Any file system access to /mnt/direc01 now freezes the process. Even sending a SIGKILL does not make it a defunct/zombie process. Surprisingly, another CIFS mount point (which I have unmounted by now) was not affected and was still functioning. I'm using Arch Linux x86_64, Linux 3.5.0, cifs-utils 5.6. There are two CIFS mounts on the same mount point due to operator accident. They were manually mounted using mount.cifs.
