e2e tests randomly fail execution in github runner with: Error: raise RuntimeError('Event loop is closed')

[rlubke]

The initial connection to Coherence is fine, but then the following error is raised:

.2024-12-19 19:02:02,752 - coherence - INFO - Session [db702d22-0620-4ce0-9485-e1e36824903d] connected to [localhost:1408].

Coherence detects the disconnect and continues to attempt to reconnect and continuing to fail with the above.

This doesn't appear to be related to a particular Python version as it randomly happens across the jobs.
