Description

We just detected an unhandled promise rejection that was triggered while issuing a command or a .execute() using a pool instance. Due to limited stack trace, I am not sure if it was a dedicated client obtained by .execute() or just a client retrieved for the execution of a single command. I am not that familiar with the internals of the Redis SDK, but I am guessing some kind of race condition within the library related to the acquisition and release of client instances for tasks, or some bug in the linked list.
