[Swift-devel] OSG hang

[Jonathan Monette]

Ok.  I set GLOBUS_TCP_PORT_RANGE and GLOBUS_TCP_SOURCE_RANGE to 50000,51000 and GLOBUS_HOSTNAME to the ec2 ip-address.  Setting these variables seemed to have resolved this issue.  I can execute Swift on the VM to sites from OSG. I can see the sleep job running on the head node of the OSG site and when it finishes Swift also shuts down.
