Failed to execute TraceDownstream in ArcGIS Pro

I have created a model that uses the "Ready To Use Tools" from Model Builder in ArcGIS Pro.  However, the model has started crashing with the following error:

 

 

There is no clear reason why it keeps crashing with the failed error "Could not service request" and "Failed to execute (TraceDownstream)."  I am able to restart the model where it left off, but after a random number of iterations it crashes again.  The number of iterations between errors is between 1 and ~130 iterations.  Are the Esri data processing servers congested?  I have run similar models in the past and they have crashed much less frequently. 

 

I need to run this hydrology modelling tool close to 15,000 times but after several days of attempts, I have only gotten to about ~300 iterations due to this failed execution when accessing this online service.  Any advice?

 

Thanks,

Roland
