Hi,

We are trying to first write to a named pipe file using one job and then read from the same named pipe file using another job having multiple input links in the job which writes.

In the above case the job which writes aborts with a broken pipe error and the screenshot for the error we get is attached in this

can you please help?

Thanks.

There's no attachment and no way to 'attach' anything anyhow. For a screenshot, you'd need to host it somewhere - and there are numerous free images hosting services - and then use Img or URL tags to link it into a post.

The named pipe mechanism requires that you have both a writer process and a reader process running at the same time. You have timeout or wait attributes that control how much time you have available before you get a "broken pipe".

So a question would be "are you certain you are running the 2 jobs at the same time?" and that you are using the same physical fifo file.

There are two threads on this subject - here is the other. Has some of the background left out of this one.
