Hi All:


Does anyone have any insight as to some logging? We're using Aspera on ios to upload some data to our servers. When transfering large files over LTE, the upload appears to stall (no data sent or received) and we see the following in the symptomsd log:


Cell traffic threshold 9442514 on flow with pid 312 procname iGateway UUID A8C9495C-709E-3ED0-9752-50BBEC7F72EC (bundle com.ctv.iGatewayUploader) EUUID EUUID-as-UUID (bundle com.ctv.iGatewayUploader proc <nil-eproc>) VUUID <nil-VUUID> (bundle <nil-vbundle> proc <nil-vproc>).


Our test file is about 31MB and it's stalling at 8MB. And the logging is pretty consistent with the stalling.


We've opened a bug with Aspera, but I'm wondering: "Does anyone know what this means?" Is it a red herring?


Thanks in advance for your time...


John

You should use an RVI packet trace to see what’s happening at the TCP level. See QA1176 Getting a Packet Trace for information on how to get such a trace.
