System completely unresponsive after role execution

[alexlawrence]

The role/playbook executes without any sign of error.

However after the execution the remote system behaves as follows:

• it is not possible login via SSH (timeout).
• ping requests produce timeouts
• custom services (e.g. NodeJS apps behind nginx) seem to load but run into timeouts
  Overall it seems that system is not able to process any incoming requests.

I could only make the server respond to anything be rebooting it. However, after a few minutes it is unresponsive again.

At first I thought it was related to the sshd config but now I´m unsure what´s causing these issues. It might even be caused by https://github.com/dev-sec/ansible-os-hardening which was also applied.

Any ideas what is happening in this case?
Do you need any additional information?

Hey @alexlawrence,

thanks for reporting this. Is this maybe the same problem as described here?

To further debug this, can you please provide the operating system used and the complete playbook you ran?

Hey @rndmh3ro,

thanks for the feedback.

After some investigation I assume that this issue is related to https://github.com/dev-sec/ansible-os-hardening That is why I will close this issue here and open a new one for the other project.

Sorry for the confusion.
