I use VirtualBox (4.1.12) on Windows 7 Ultimate SP1. The guest is Linux (kernel 3.3.2, cifs-utils 5.3), which I boot directly from a partition. If I use CIFS to access the Windows partitions, the connections constantly hang and the applications to access it deadlock until killed. For example: $ cd /mnt $ ls It hangs (the share in question is mounted under /mnt/ntfs2). 'ps' returns "3174 pts/0 D+ 0:00 ls --color=auto" and the load average increases until I 'kill -9' the process. The only message I get in the logs is "CIFS VFS: Server 192.168.1.64 has not responded in 300 seconds. Reconnecting..." After that, the share only works if remounted. I don't know what's causing it, but it works perfectly from VMware Player using the same setup, so it looks like a bug in VirtualBox, not in CIFS ? This isn't a new issue, as I started using VMware Player in July 2011 after giving up getting CIFS to work reliably with VirtualBox. I'm attaching a log created with 'echo 7 > /proc/fs/cifs/cifsFYI', just in case it helps, and am willing to do other things to, it not solve it, at least know what to blame. At 14:26, I killed both 'ls' processes and unmounted the partition.
