Just upgraded from 5.4.13 to 5.6.4. most everything went swimmingly.

We do have an NRPE check failing.

Here is failure message in service status - Could not construct return packet in NRPE handler check client side

Here is entry in client side log - error:modules\NRPEListener\NRPEListener.cpp:317: Exception handling NRPE packet: Invalid packet version.

Client is NSClient++ - 0.3.9

Here are arguments - $ARG1$ CheckCounter $ARG2$ -a "Counter=\\MSExchangeTransport Queues(_total)\Messages Queued For Delivery" ShowAll MaxWarn=300 MaxCrit=950

Try passing a "-2" to your command to see if this is going to fix the issue. For more information on the topic, see this post:

Perfect! That did it.

On a side note, configuration verification in CCM is taking a lot longer than before the upgrade, maybe 15 seconds or so.

I am glad I was able to help!

On a side note, configuration verification in CCM is taking a lot longer than before the upgrade, maybe 15 seconds or so.

The latest version of XI has a lot more options than XI 5.4.13, and may require a bit more resources. The length of time to apply configuration may depend on many different things. Even though, it is a big jump in version numbers, the config verification shouldn't take any longer. However, if you had a large BPI config (lots of BPI groups) on this instance, and user-based CCM permissions, it would take a bit longer to apply configuration.
