Create stress tests for TaskManager and coroutines

[jr0me]

Description

We identified segfaults and exceptions when processing an unusually high volume of events, far beyond typical operational scenarios. While these cases may be improbable, we want to ensure the system is robust under extreme conditions.

This task involves designing and implementing stress tests to simulate scenarios with:

Excessive numbers of events to uncover potential crashes or unexpected exceptions.
Repeated starting and shutting down of the agent to verify stability and correct behavior.
The goal is to bring any hidden issues to light and improve the overall resilience of the system. By running these tests regularly, we can prevent such errors from reoccurring in the future.
