Check the queue manager is started and if running in client mode, check there is a listener running. Please see the linked exception for more information.; nested exception is com.ibm.mq.MQException: JMSCMQ0001: WebSphere MQ call failed with compcode '2' ('MQCC_FAILED') reason '2537' ('MQRC_CHANNEL_NOT_AVAILABLE').

You really shouldn't just dump errors in a stackoverflow question with no explication. I would suggest you find out what the queue manager error logs show. You could have hit maxinst, or max channels, the channel could have been put in a stopped status, could be other reasons. — JoshMc
sorry about that, to look into queue manager logs - do i need to install IBM MQ client? — Nagendra Busam
No you need to log into the queue manager server and review the logs, if you do not have access then you would need to ask someone who does. — JoshMc

The client side of your connection has reported the following error:-

JMSCMQ0001: WebSphere MQ call failed with compcode '2' ('MQCC_FAILED')
reason '2537' ('MQRC_CHANNEL_NOT_AVAILABLE').

This could be for one of the following reasons:-

The channel is currently in stopped state.
The channel has been stopped by a channel exit.
The queue manager has reached its maximum allowable limit for this channel from this client.
The queue manager has reached its maximum allowable limit for this channel.
The queue manager has reached its maximum allowable limit for all channels

as described in the explanation of 2537 (MQRC_CHANNEL_NOT_AVAILABLE) in IBM Knowledge Center.

As it also says in that explanation, you should examine the queue manager and client error logs for messages explaining the cause of the problem.

If you don't understand what the issue is when you read the AMQERR01.LOG files on both client and queue manager machines, please update your question with the relevant error message and we can give further help.
