[Matthew Shaxted]

Hi All: I was able to get the runs working successfully by changing the maxtime flag in the sites file.

Thanks

Subject: Channel Timeout on Beagle?

Hi Swift Users:

I am running some studies on Beagle using Swift, and experiencing a strange error. The Swift scripts run great on cloud and on the Beagle login node, but seems to be timing out for some reason.

Does anyone have insight into the cause of this? Thanks for any help.

Below is the error I am getting:
