Every now and then we get this error on our production servers

```auto
2020-01-06T16:02:57.941Z mediasoup:ERROR:worker[pid:22] (stderr) Assertion failed: current_timestamp_group_.complete_time_ms >= 0 (../deps/libwebrtc/libwebrtc/modules/remote_bitrate_estimator/inter_arrival.cc: BelongsToBurst: 146)
2020-01-06T16:02:57.965Z mediasoup:ERROR:Worker worker process died unexpectedly [pid:22, code:null, signal:SIGABRT]

```

The version of mediasoup we are using is 3.5.4. We haven’t been able to reproduce this on local environment.
