Sometimes, agent is blocked until restart

Sometimes, the agent is blocked and output messages like below endlessly.

2024-04-16T09:01:06.299901+02:00 janey2 argos-agent[4951]: Retrying: attempt 10041 ended with: <Future at 0x7f07643bfe50 state=finished raised RuntimeError> Cannot reopen a client instance, once it has been closed.

The only way to unblock it is to restart.

Do you have an idea on the source of the problem, by any chance?
