neptune-client: BUG: Error msg during training - Timestamp must be non-decreasing for series attribute

Describe the bug

When running Neptune logger in PytorchLightning with ddp > 1gpus. Then there are continuous errors reading Error occured during asynchronous operation processing. Timestamp must be non-decreasing for series attribute If the Neptune logger is offline, or if neptune logger is removed then this error isn’t logged. There are too many errors, and even the progress bar of the training is difficult to identify.

Reproduction

When i run with 4gpus, i was able to reproduce this. https://colab.research.google.com/drive/1TOadmpet63eSXz6LMHVvdM-D6Gy0LDxe?usp=sharing

Expected behavior

If this is a valid error message, then there is no hint of what actions needs to be taken. If they are harmless/not valid kindly suggest a way to suppress this print.
