Blocked on semaphore

Is there a way to track down what processes are sharing semaphores? Specifically, I have a pid that is 100% blocked on semaphore and I would like to see if another pid holding the semaphore is hung. Thanks.

Re: Blocked on semaphore

You can get some information by doing "ipcs -sa", but I don't think it will give you the blocking information.

Re: Blocked on semaphore

Thanks, the script is useful, but is there a way to show which semaphore ID a process is waiting on?
