There is some timeout, if watchdog does not receive reply within that timeout, these events are generated. In this case after 15 milliseconds after the error was generated watchdog received reply from the thread which resolved the error.
This could be if there's high CPU and/or RAM usage on the system. Check monitoring data on CPU and RAM consumption on your server.
