Description
There have been several scenarios where renewing a stitched sliver results in the circuit status for the ION aggregate to go from "ready" to "failed".
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" }}}

RenewSliver translates into Modify in Internet2 OSCARS. I have seen it before that Modify succeeded and then circuit transitioned into Failed status. We should ask OSCARS developers to address two issues:
- OSCARS does not acknowledge Modify failures properly.
- Refusal of Modify request causes circuit failure.

Writing this ticket to track problem resolution from OSCARS developement.

This was an issue in OSCARS. Andy Lake from ESnet made a patch to the code. After we applied the patch to ION, we on longer see the problem.
