Hi there!
I'm writing C++ application that uses XMS to send/receive messages. After I receive message I want to iterate over its properties to process their names/values. To do so, I used the following code:
| Code: |
for (xms::Iterator it=lpMsg->getProperties(); it.hasNext(); ) {
xms::Property *prop=reinterpret_cast<xms::Property*>(it.getNext());
// Do something with prop->name() and other prop members
delete prop;
}
|
However, I get memory leak in lpMsg->getProperties(). I'm using umdh Windows tool to check if it's actually memory leak.
lpMsg is properly deleted after that. I'm using latest XMS version (2.0.4).
What am I doing wrong? Any input or suggestion would be highly appreciated. |

Which version of the MQ client did you install to get that?

I'm using MQ 9.1, but as far as I remember, I've installed XMS 2.0.4 separately from IBM site.
BTW, I tried IBM samples, provided with XMS, and C sample (SampleConsumerC.c) leaks just fine. It's not just very apparent due to low TPS. |

If the IBM supplied XMS library leaks using the IBM supplied source code, then it's nothing you're doing.
PMR time.

Wrong installation! Uninstall XMS and install the full client with messaging services (JMS/XMS) from IBM. XMS is now part of the product and should not be installed alone!. Try again and see if the leak has been fixed.
