Service discovery is not happening in AS3

Question

We are having AS3 running in our F5 BIGIP and we are facing an issue with the service discovery.The pool members are unable to Autodiscover the new ip and port when the application containers are restarted.--&gt; I can be able to see the auto discovery is happening in CLI (meaning after the application container is restarted, I can see the new Ip, and port is reflecting in the CLI. I am checking this using the command curl -vk http://&lt;consul IP&gt;/&lt;endpoint URI&gt; | jq .) and that auto discovery is not happing in GUI. As the pool members are not auto discovered and not attach to the pool, the pool is showing down and the users are getting impacted.&nbsp;--&gt; I have reinstalled the AS3 in our F5 and the issue remains same. Currently the AS3 version we are running on 3.47&nbsp;--&gt; I can be able to see the declaration in the GUI (https://&lt;BIG-IP&gt;/mgmt/shared/appsvcs/declare)--&gt; Service discovery is enabled in our F5. (https://&lt;BIG-IP&gt;/mgmt/shared/appsvcs/settings)--&gt; We have tried by increasing the memory of 1GB to REST API interface, but the issue still remains same.We have increased the memory to 1Gb&nbsp; for the belowlist sys db provision.extramblist sys db provision.restjavad.extramblist sys db provision.tomcat.extramb--&gt; Currently our F5 LTM is running on version 16.1.5 and we have tried upgrading to version 17.1.2.1 to check if this issue can bel resolved or not but after upgrading the complete AS3 services are down (the service discovery did not happen and because of that I see all the virtual servers are in down state).&nbsp;--&gt; We are having Active -Standby setup, we have tried by failover but the issue still remains same.&nbsp;--&gt; We have tried restarting the belowbigstart restart restjavad restnodedbigstart restart restjavad restnoded httpd tomcatCould someone please help here to overcome this issue. This issue has been running from past 30 days, and we don't have any solution from F5 TAC.Regards,Bharath Kumar&nbsp;

Hi bbharatkumar09,

Have you tried examine the restnoded failure log at /var/log/restnoded/restnoded.log for any error messages. This log can provide insights into what might be going wrong.If you haven't already, try uninstalling and reinstalling AS3, ensuring that all related packages (like f5-appsvcs-discovery and f5-service-discovery) are correctly installed.
