Re: Causes for process going into D state

What are the causes for process going in to D state. (which is
interruptible).

The process is doing an uninterruptible sleep in the kernel. The most
common cause of this is that it is waiting for a disk I/O-request to
complete.

in my program i am using down(struct semaphore *) function which
places process to uninterruptible state. so I am seeing Process in D
state.

You could use down_interruptible instead, although that likely
wouldn't solve your problem.
