I have a problem when 40 devices try to join in my Zigbee network. 
 My problem is very similar at this topic:

&lt;p&gt;Great! :) Let me know if it helps. Otherwise I guess it would work to simply reset it when the nRF doesn&amp;#39;t respond, though hopefully we&amp;#39;ll avoid&amp;nbsp;doing it that way.&lt;/p&gt;

&lt;p&gt;Hi Elfving, yes I&amp;#39;ve tried to use the configuration alternatives, and with:&lt;br /&gt;&lt;br /&gt;&lt;span&gt;CONFIG_NRF_802154_RX_BUFFERS set to 64&lt;/span&gt;&lt;br /&gt;&lt;span&gt;ZB_CONFIG_IOBUF_POOL_SIZE defined to 127U&lt;/span&gt;&lt;br /&gt;&lt;span&gt;ZB_CONFIG_SCHEDULER_Q_SIZE defined to 127U&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;some devices were able to join in the network, but only about 10 of 50..&lt;br /&gt;After the Nordic seems blocked and only with a reset is possible to recover it.&lt;br /&gt;&lt;br /&gt;Now I resolved with a &amp;quot;ping&amp;quot; from my main microcontroller to the Nordic. When he doesn&amp;#39;t answer, I reboot it, and I open the Zigbee network again. Some devices at the time, I am able to join all devices.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;/p&gt;
[quote userid="103347" url="~/f/nordic-q-a/105786/coordinator-problems-during-commission-of-40-devices/459373"]If you do get asserts, it might be that you&amp;#39;ve gotten the&amp;nbsp;known &lt;a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/releases_and_maturity/known_issues.html#zigbee"&gt;ZigBee issue &lt;/a&gt;&lt;span&gt;&lt;a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/releases_and_maturity/known_issues.html#zigbee"&gt;KRKNWK-12115&lt;/a&gt;.

&lt;p&gt;Could you try implementing the workaround described there and see if it helps?&lt;/p&gt;

&lt;p&gt;Any development in the issue from your side?&lt;/p&gt;
[quote user="Marco_A"]How can I do to see the assert messages?[/quote]
&lt;p&gt;It should pop up along with the log if there&amp;nbsp;are any asserts, I guess that is what you get on UART. If you are not seeing any when trying to add these devices then my guess is that this is similar but not exactly the issue described in the other case.&lt;/p&gt;
&lt;p&gt;Have you also tried the other &lt;a href="https://devzone.nordicsemi.com/support-private/support/275662#permalink=706903"&gt;configuration alternatives listed by sebr here&lt;/a&gt; to see if any helped?&amp;nbsp;&lt;/p&gt;

&lt;p&gt;Understandable. And we will still try to help you of course.&lt;/p&gt;
[quote user=""]&lt;p&gt;My problem is very similar at this topic:&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;[/quote]
&lt;p&gt;So&amp;nbsp;the case you linked to is also similar in the fact that if you add the devices slowly, you get less issues adding them? Do you run into the same assert that they do in the other case, or only the situation where you do not get any events?&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Could you try it with this memory config?&lt;/p&gt;
&lt;p&gt;&lt;a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/5314.zb_5F00_mem_5F00_config_5F00_custom_5F00_max.h"&gt;devzone.nordicsemi.com/.../5314.zb_5F00_mem_5F00_config_5F00_custom_5F00_max.h&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;First of all, if this is a new development for new devices, I would recommend you to switch to the nRF Connect SDK for this development.&lt;/p&gt;
&lt;p&gt;&lt;a href="https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/nrf-connect-sdk-and-nrf5-sdk-statement"&gt;Here is one reason&lt;/a&gt;, though another is that the Zigbee SDK is not just old, but deprecated.&lt;/p&gt;
