[TheLester]

I am using okhttp 3.8.0 and getting a lot crashes in crashlytics with this stacktrace

Fatal Exception: java.util.concurrent.RejectedExecutionException: Task d.bh@33f4a51 rejected from java.util.concurrent.ThreadPoolExecutor@63d82b6[Shutting down, pool size = 5, active threads = 5, queued tasks = 0, completed tasks = 22]

What colud be the reason of this ?

You called shutdown on the dispatcher’s ExecutorService while it still had calls outstanding.

Maybe we should handle this error and call Callback.onFailure() with a cancelation? That would be pretty reasonable.
