There maybe some type of timing issue, this problem does not occur on every attempt. Problem has also been seen with different topologies (IG MAX to IG GPO, and with PG UKY to Missouri IG) Here is a failure which shows up after the renewsliver: ((( ""geni_urn"": ""urn:publicid:IDN+ch.geni.net:ln-prj+sliver+ig-max-ig-gpo_vlan_ion.internet2.edu-60581"", ""geni_error"": ""Coordinator(PATH_MODIFY_FAILED): 'Path modify failed with error from PSS'"", ""geni_status"": ""failed"" }}} According to Xi: On 1/27/14 1:52 PM, Xi Yang wrote: > RenewSliver translates into Modify in Internet2 OSCARS.
