Description

Synchronization of mnTestSEAD objects results in "NULL" exception on cn-stage.test.dataone.org in cn-syncrhonization.log. The "NULL" exception limits diagnosing the issue.

Observation of mnTestSEAD MN as of 6 April:

Science metadata is FGDC-STD-001-1998 format

There are no resource map or data objects

There are no relevant log messages in either /var/lib/tomcat7/logs or /var/metacat/logs

See attached file for a list of the mnTestSEAD object list and relevant section of the cn-synchronization.log file from 6 April.

Additional information from Skye on 17 April:

One SEAD error found today, regarding their newest content:

Looks like an FGDC schema validation failure for this particular object.

However I also looked at some other objects that Mark noted and see the same error Mark saw - for example:

cn-synchronization.log.1:[ERROR] 2015-04-07 00:30:51,911 (TransferObjectTask:write:606) Task-urn:node:mnTestSEAD-seadva-PowerMaryE.d6664a9f-322a-4551-980b-62b44c222162
cn-synchronization.log.1-null

The ’null' line corresponds to a logging message where the exception should be printed out, but we are just seeing ‘null’ in the log.

I think Robert may need to take another look at these sync failures. When I first started playing with the test SEAD yesterday I was getting a bunch of timeouts on REST endpoints - then at some point they started working. Im wondering if some of the sync failures may be related to timeouts? Although I think Mark has tried harvesting from this test SEAD node a few times?

The error in question occurred in code that has long since been replaced. I have searched synchronization logs going back as far as last November and do not see an occurrence of the error. So, I'll say it is closed.
