Pods of user-simulator get OOMKilled

[W3D3]

Environment

• Client OS (e.g., Linux, macOS, Windows): Kubuntu 22.10
• Unguard Version [e.g. 1.0.0]: 0.7.0
• Kubernetes version (kubectl version): 1.25

Describe the bug
Pods of the user-simulator deployment will periodically run out of memory before they terminate on their own and then be killed by Kubernetes (OOMKilled event). In some instances K8s will then back off from restarting them, making them not generate any load until they are manually restarted again.

To Reproduce
Deploy unguard and let the user-simulator run for some time.

Suggestion
Making the user-simulator a Kubernetes cronjob would make it more resilient against crashes, as there may be a memory leak in a library used by the user simulator.
