Run hanging on request for unknown reason

Running a hyperdrive run with a pytorch model I have some of my child runs hanging with a request in the log as below:

2022-04-20 12:27:52,149|azureml.BatchTaskQueueAdd_1_Batches.WaitFlushSource:BatchTaskQueueAdd_1_Batches|DEBUG|[STOP]

2022-04-20 12:29:11,739|azureml.core.authentication|DEBUG|Time to expire 1813550.260178 seconds

Expected behaviour:
Run to complete and give metrics

Actual behaviour:
Log shows run is hanging and not posting metrics

Any help with why this is happening is appreciated (or if this is posted in the wrong place I am happy to be directed to the correct place to post this issue)
