TCP/IP error 78 (0x4E) on AIX is ETIMEDOUT. Tell your network staff that your MSCS cluster IP address is returning ETIMEDOUT. There is nothing you can do to fix this in MQ. MQ is just calling the TCP/IP stack and is getting the reported error.
One test that people like to do to take MQ out of the picture and show it is just a network error is to try a TCP ping of the IP address in question. Have you tried that check?
If you want to work around this problem until your network people fix the MSCS cluster IP address, you could change the CONNAME to have a comma-separated list of the node IP addresses, just in the mean time. Then it will try each one until it find the one that works.

Subject: Regarding AMQ9202 error
Hi ,
My sender channel is retrying state for few hours. I checked the connection name and MQ log.
I gave the MSCS cluster IP(172.19.59.59) and port, Last one year it was working fine. Now we are not able to start it and find below error .
MSCS cluster has two node. If i have hardcode one node IP then i am able to start the sender channel. Please guide/help me if i will use MSCS cluster IP not node(system)IP and my sender channel will start. how it was working earlier.
