I've run up against this twice now. Linux forgery 2.6.32-22-server #36-Ubuntu SMP Thu Jun 3 20:38:33 UTC 2010 x86_64 GNU/Linux
The box is running smbd with the only share being on a dmcrypted partition. I have a dozen Windows systems running everything from Win2k to 2k3 pushing nightly NTBackup dumps to the box. These dumps generate 9GB to 250GB files that are streamed to the box, and then read back by the host windows system to verify the dump. This works cleanly for about a week, when it fails one or more smbd processes will be pegging the cpu, along with a flush process. Any attempts to kill those processes hangs the shell, as does trying to do anything with the file system in question. Trying to reboot or shutdown -h also just hangs the current shell.
