Comment 2 Andy Walsh 2017-11-14 19:17:38 UTC 
This looks like it might be a duplicate of BZ 1510176.
Comment 3 corwin 2017-11-14 21:07:33 UTC 
Upgrades from version 6.1.0.34 to version 6.1.0.46 are not supported. Upgrades will be supported probably from version .46 and certainly from whatever version ends up in the beta code freeze to subsequent 6.1 versions.
Comment 5 corwin 2018-07-11 17:39:14 UTC 
This issue only applied to the specific release and is no longer an issue.
Comment 6 Andy Walsh 2018-07-16 02:39:12 UTC 
Not MODIFIED, but CLOSED.
