Use this information to understand the IBM MQ client on HP Integrity NonStop Server error logs, together with an example.
At installation time, an errors subdirectory is created in the MQ_INSTALLATION_PATH/var/mqm file path. The
errors subdirectory can contain up to three error log files named:
AMQERR01.LOG
AMQERR02.LOG
AMQERR03.LOG
As error messages are generated, they are written to AMQERR01.LOG. When
AMQERR01.LOG gets bigger than 2 MB (2 097 152 bytes), it is copied to
AMQERR02.LOG. Before the copy, AMQERR02.LOG is copied to
AMQERR03.LOG. The previous contents, if any, of
AMQERR03.LOG are discarded.
The latest error messages are therefore always placed in AMQERR01.LOG. The
other log files are used to maintain a history of error messages.
To examine the contents of any error log file, use your system editor. The contents of the log
files can read by any user, but write access requires the user to be a member of the mqm group.

04/30/13 06:18:22 - Process(320406477.1) User(MYUSER) Program(nssfcps_c)
Host(myhost)
VRMF(7.1.0.0)
AMQ9558: The remote channel 'SYSTEM.DEF.SVRCONN' on host 'hostname
(x.x.x.x)(1414)' is not currently available.
EXPLANATION:
The channel program ended because an instance of channel 'SYSTEM.DEF.SVRCONN'
could not be started on the remote system. This could be for one of the
following reasons:
The channel is disabled.
The remote system does not have sufficient resources to run another instance of
the channel.
In the case of a client-connection channel, the limit on the number of
instances configured for the remote server-connection channel was reached.
ACTION:
Check the remote system to ensure that the channel is able to run. Try the
operation again.
