Unable to load dynamic library 'appdynamics_agent.so'

Bhanu_Persaud — Sun, 12 Feb 2023 22:41:58 GMT

I'm having issue where php can't seem to load the agent.so, similar to this issue PHP 8.0 agent cannot start - AppDynamics Community

Is there any know bugs with the current php agent version 22.12.1 with php 8.1

I've followed install instructions as usual from Install the PHP Agent by Shell Script (appdynamics.com)

php -v
PHP Warning: PHP Startup: Unable to load dynamic library 'appdynamics_agent.so' (tried: /usr/lib64/php/modules/appdynamics_agent.so (/usr/lib64/php/modules/appdynamics_agent.so: undefined symbol: zend_vm_stack_copy_call_frame), /usr/lib64/php/modules/appdynamics_agent.so.so (/usr/lib64/php/modules/appdynamics_agent.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

Hi @Bhanu.Persaud,

Since this might be a bug, it's best if you contact Support. How do I submit a Support ticket? An FAQ

Can you followup here what you hear from Support?

Hi @Ryan.Paredez

I've already open a support ticket. They were able to replicate the problem and currently investigating. Support did recommend a roll back of php as a workaround but unfortunately that's not an option for us.

I will update this thread once a resolution is reached.

AppDynamics has provided us with a fix and is now part of the latest public release php agent ( 23.2.0.684 ).
