More than likely you have some channel definition or network access problem. Check your channel definition on the sender. Also, check your network connectivity from the sending machine to the receiver.

| Make sure that the sequence numbers are also reset prior to trying to restart the sender channel. |

Looking at the MQ error logs might be helpful.

Summarizing what geeks said above:
First, check the channel definition. Most likely, it may be typo.
Second, Check network access problem. Issues ->telnet hostname port whether i can connect to the host
Thirdly, check channel sequence number may not be matched because you created/updated one chanel definiton recently
Fourthly, see the error log and find what it says, and fix that
Fifth, if the above steps do not lead you to a solution, come back to this forum with more and detailed informaiton
Hope this helps |

You say you checked receivers on both channels? This sounds like you are looking at more than one channel pair.
A single sender channel connects to a single receiver channel - both of which have the exact same name. The reciever end of the channel needs a listener running. Sender channels do not have listeners running.
Look only at the sender channel - the one pointing to the transmission queue where your messages are accumulating.
Compare the sender channel name and receiver channel name - they must be exactly the same. Check that the transport types are exactly the same - usually TCP. Check that the sender channel CONNAME attribute has the ipaddress(port) of the receiver-end listener.
As stated in replies to your post, verify that you can c: or $ ping from the sender to the receiver. Verify that you can (from runmqsc) PING from the non-started sender end of the channel to the receiver.
Have deleted and re-DEFined either the sender or receiver channel? This is frequently the cause of channels in retry. |

How can you have client or binding on a sender/receiver pair? 
Do you mean normal or fastpath?

One way of resolving what the exact problem is could be defining a dead letter queue.
If the dead letter queue is not defined,and if the MCA is unable to put a message through, it is left on the transmission queue and the channel is stopped.
have you defined a DLQ?? if the messages go to the DLQ then atleast we would be sure that there is no problem with the channel...or otherwise.
...just a hunch...the GrandMasters/Masters would guide you better...

Ashu |
