Same here...
Happening every time we try using a ParallelAgent with sub_agents created at runtime.

what i did was just create a patch in the library that removes the error logging in the exception - i still see the logs of my traces and the code of the agents works fine

We’re seeing this issue quite frequently during peak hours, while it occurs less often at night or on weekends.
