| Basically as the title suggests I'm having an issue with the Open input count growing on my backout queues. I have a queue X and X.error which is the backout queue. The open input count on X.error is upto 25 in my production environment and wondering what is causing it to be so high. Thanks in advance |

You have offered very little information here.
Have you look at QSTATUS to see what applications have the queue open for input?
Is the queue triggered?

I've had a look at the queue status
App Name : WebSphere MQ Client for Java
App Type : Queue Manager
App Desc : WebSphere Mq Channel
Channel Name : (Channel to WAS Deployment Manager)
Queue is not triggered |

First, did you really mean open input count, or message depth?
If open input count, then DISPLAY QSTATUS should show you 25 handles open for input.
Each of those is for an application using your queue.
Do you have 25 applications getting from your queue? If this is unexpected, work with the owners of those 25 applications.
It is possible this is not a problem at all. Can you explain why you think it's a problem in your environment? |

| Open input count. There are no applications connecting to these backout queues that's why i'm confused as to why there is a count of 25 |

Some applications have 25 open handles. But you say (if I understood your reply) that no applications are using the queue. Please copy your evidence into this thread. |

From my understanding that's right. It's a backout queue for a queue that has connections to applications. But no applications are directly connected. I have had to restart the queue manager as the max no. channel had been reached |

No queue will have connections to applications, however, I'd hazard that the WAS Deployment Manager channel isn't being closed properly and it's the Deployment Manager that is opening the back-out queue.

Thanks this sounds like the only likely explanation |

And you would still see this via 25 entries in DIS QSTATUS TYPE(HANDLE) output.
They would probably all say "java" or similar.
Do you have 25 entries in DIS QSTATUS for this queue? |

I restarted the queue manager. But at the moment there is only 1 open output count on the backout queue. |

Is that all you did - restart the qmgr? Did you also start applications?

The applications were already running. I didn't restart them |
