Probably someone else is holding the same lock for some
reason and is stuck in a file system syscall.

Under Linux you would look at /proc/locks to find that info,
no idea how to find the current lock holder under Solaris.
You need to find that one and see what syscall that guy is
stuck in.

BTW, you don't happen to run something like samfs?
