/lib64/liboneagentproc.so symbol lookup error

Update

=======

It was very simple. I just had to upgrade our amazon-ssm-agent 🙂

Question

========

I would like to know how critical /lib64/liboneagentproc.so is. It's because when I installed Dynatrace Oneagent in an Amazon-Linux-2 running amazon-ssm-agent, the amazon-ssm-agent systemd service failed to start. The error that shows up when I run "systemctl status amazon-ssm-agent" is

Mar 11 00:35:19 apiproxywebapps-07cd-172_20_19_167.us-east-1.dev amazon-ssm-agent[12552]: /usr/bin/amazon-ssm-agent: symbol lookup error: /lib64/liboneagentproc.so: undefined symbol: __environ

Once I delete /lib64/liboneagentproc.so, the amazon-ssm-agent will start fine. The oneagent systemd service also starts fine after restarting it.

However, I'd like to know the proper solution.

Thank you,

Neil

@rcamara Thanks for sharing this out!!

This is a major issue for teams using AWS SSM agent for access to their servers and deleting the file causes error messages to be displayed in the console. Can the Dynatrace team provide some guidance on this issue?

Hi, any info this issue?

[HannahM]

did you upgrade amazon-ssm-agent? Did that not resolve this behaviour for you?

[bJohnson · Accepted solution]

The latest version (v 3.1.1188.0) of the SSM agent has this issue. I was able to confirm that the issue is not present on SSM version 3.1.1141.0.

UPDATE: This issue is resolved in SSM agent v3.1.1208.0.

[HannahM]

That's great. Thanks for confirming. I can see that there was some work to resolve this to work on higher versions with OneAgent 1.237. What version are you using?

[bJohnson]

We are using One Agent v1.233.190.20220314-111259

[HannahM]

OK, thanks. So it looks like SSM version 3.1.1141.0 is the one you will need to use until you update your OneAgent to the latest, 1.237.
