It'd probably be helpful if - assuming you're running a recent Samba
version - you can attach to the winbind process with GDB when it gets
stuck and post a backtrace, so that the devs can see exactly where the
problem is.  No doubt the corrupted .tdb files are causing an infinite
loop somewhere.

What version of Samba are you running?

Cheers,
