Describe the bug

FloatingPointError: overflow encountered in multiply

Looking through the code, it would appear as though this is happening while combining each of the memory logs into the omnibus memory log. From what I can tell, the reported time in one of the the files is causing an overflow error. I saw that all of the needed output files had been created, so I suggested the modeler running the model run resume it after ActivitySim model, which worked just fine (the results were close to similar scenarios that had been run).

To Reproduce
I'm not completely sure how to reproduce it. I tried copying all of the logfiles into a separate folder and running a Python script that replicated what ActivitySim was doing, but that worked just fine (I still have the folder saved and can share it with anyone who would like to see it for debugging purposes).

Expected behavior
The memory logs should be combined into the omnibus memory log without any issue.

FloatingPointError: overflow encountered in multiply

Looking through the code, it would appear as though this is happening while combining each of the memory logs into the omnibus memory log. From what I can tell, the reported time in one of the the files is causing an overflow error. I saw that all of the needed output files had been created, so I suggested the modeler running the model run resume it after ActivitySim model, which worked just fine (the results were close to similar scenarios that had been run).
To Reproduce

I'm not completely sure how to reproduce it. I tried copying all of the logfiles into a separate folder and running a Python script that replicated what ActivitySim was doing, but that worked just fine (I still have the folder saved and can share it with anyone who would like to see it for debugging purposes).
Expected behavior

The memory logs should be combined into the omnibus memory log without any issue.
