I have some process that is in uninterruptible sleep due to limited memory. After I kill other processes, there is enough memory available for it now. How do I change the status of the process from uninterruptible sleep to normal running? Or the OS will automatically make the change? Or do I have to kill it and start it agian? Thanks and regards!

How do you know that it is memory that is what causes it to go into uninterruptible sleep? –  Kevin M Jan 5 '10 at 16:59
    
I see the top for available memory and swap. I know how much the process will need. –  Tim Jan 5 '10 at 17:07

Uninterruptible means uninterruptible. You can't kill it without a reboot and you can't force a status change. If the state that is causing this resolves itself or a timeout expires, the process should resume. You may have some other I/O that is blocked and causing this or it may be a bug.
