Troubleshoot Podman Installation - User Guide - 2 - Cortex XPANSE - Cortex - Security Operations

Script failed to run: Docker code runner got container error: [Docker code script is in inconsistent state, ... error: [exit status 126] stderr: [Error: OCI runtime error: crun: create keyring ...: Disk quota exceeded]

By default, Podman creates a keyring that is used by each container. The limit per user on the machine might be low and Podman can reach the limit when running more containers than the keyring limit. To check the keyring usage, run the sudo cat /proc/key-users operating system command.

The command returns the usage for each UID (to retrieve the demisto user UID, run id demisto ). The fourth column shows the number of keys used out of the total number available. For more information about keys, see Kernel Key Retention Service.

You can either increase the limit of max keyrings (increasing to 1000 is safe and reasonable) per user as specified by your Linux vendor documentation or you can disable keyring creation by Podman. We recommend disabling keyring creation, unless keyrings are used by Podman in other applications on the machine. To disable keyring creation by Podman, modify the containers.conf file and add the option keyring = false under the "[containers]" section. For more information, see the Containers Engine Configuration File.

In some cases, if the Podman process crashes or is killed abruptly it can leave containers on disk. You might see errors such as error allocating lock for new container: allocation failed; exceeded num_lock when the maximum number of locks used to manage containers is exhausted due to the unused containers that remain.
