I have a program in C# that's interfacesing with WMQ for doing Request/Reply. The other day I enabled MQTrace for this application and saw bunch of MQRC_TRUNCATED_MSG_FAILED error in MQ Trace. My reply mesages size varies anywhere from 1KB to 15 KB. Does anyone know what's the default size of the buffer that's passed intially when doing MQGET call in C# and can we change it?

Hmmm... Missed this one 
It depends on which get method you call:
| Quote: |
| public void Get(MQMessage message, MQGetMessageOptions gmo, MQINT maxMsgSize) |
Allows you to set the max size. If you supply 0, or call:
| Quote: |
public void Get(MQMessage message, MQGetMessageOptions gmo)
or
public void Get(MQMessage message) |
then the first mqget is done with a 4K buffer, and if you get truncation then the buffer supplied is resized to that size, and subsequent gets will use that size (ie a dynamic buffer per MQQueue object). |

hmmm ... thats interesting. I need to go back and check which method the developer is calling. I'm sure he is not calling the first method where maxMsgLength is passed.
Thanks for your help!
