Description

A stitcher createsliver from IG GPO to IG Utah was started 7:45 which generated 51 attempts at getting resources from ION/Internet2 aggregate. All 51 attempts failed and the sliver eventually failed at 9:16.

Following are the warnings for the 51 attempts and the final error, full log is also available:

Email thread suggests that ION was creating the circuits, and then the AM was deleting them. Why?

And then all the requests starting making the routers too busy. So they've asked us to back off.

But we still don't know why the circuits were failing.

This still needs investigation. One theory is that OSCARS creates the circuit. However, ION AM had failure after trying too many times of status query to OSCARS. This may not due to circuit failure but OSCARS API failure. Once a failed status is established ION AM will no longer query OSCARS.

I suggest increasing the query interval to 30 secs or 1 minute to see if that helps.

Priority: majorblocker

Stitcher has been modified to wait a full 10 minutes between ION AM calls, which slows testing down drastically.

Using this new version of stitcher, this problem still exists and no slivers can be created with the ION aggregate in the path.

How about manually submitting the rspec to ION AM and then manually check sliverstatus using omni.py ?

Please attach the request rspec. I will try it with my test AM.

comment:5 Changed 11 years ago by lnevers@bbn.com

Tried manual create sliver 3 times today and all 3 worked. Tried 3 stitcher createsliver attempts and they all failed. Attaching the 2 RSpecs:

  • stitch-ig-gpo-ig-utah.rspec - RSpec generated by me and used with stitcher to request the failure scenario being investigated by this ticket.
  • lnstitch1-createsliver-request-11-ion-internet2-edu.xml - RSpec generated by stitcher when it attempts requests for I2/ION aggregate and used for the manual request.

Attaching log of latest test run which which uses:

  • 300 seconds sleep between reservation attempts at ION or another DCN based aggregate
  • 60 seconds sleep between sliver status calls at ION or another DCN based aggregate

Fixed a bug in AM Java core code that could report false "FAILED" VLAN status.

This only happens by special timing of sliverstatus query.

BTW, the stitcher does not seem to respect the option "--ionStatusIntervalSecs 60". It still tried SliverStatus every couple of seconds.

Reassign to Chad to update the Java code via SVN and restart tomcat on ION AM.

Huh - you're right, that was a bug in stitcher, that I've now fixed.

I have re-ran the test with the stitched sliver from IG GPO to IG Utah using using the original sliver status timing that used to cause the failure. The sliver was created successfully and the problem seems resolved. Is there anything else that needs to be done? If not, this ticket can be closed.
