The problem occurs whenever MQMonitor sends huge queries to MQ server. Then the MQ server will not able to handle the responses properly. In such cases, it throws the exception error and MQMonitor starts reporting 2235 error after that.


To make the MQ server handle the responses properly, Engineering created functionality to divide the huge query into number of small queries and send each one separately, by making use of regex in the file. The issue is fixed in APM 10.5 SP2 and above.

The regex is edited to address these portieres on the file.

<Queue Manager>@<Host>.queue.filter.includeonly.regex
<Queue Manager>@<Host>.channel.filter.includeonly.regex
