Issue notes not being saved

I am trying to write some “notes” on an issue (aka comment on an issue)

but for some reason the comments are not being saved to the database. (I manually connected and checked the notes table, only older notes are saved in there.

Looking at the production log, i see that notes are getting “OKed” from the app:

Started POST "/Nate/sample/notes" for at 2016-02-29 19:35:44 +0000
Processing by Projects::NotesController#create as JSON
Parameters: {"utf8"=>"✓", "authenticity_token"=>"[FILTERED]", "view"=>"inline", "line_type"=>"", "target_type"=>"issue", "target_id"=>"43", "note"=>{"commit_id"=>"", "noteable_id"=>"43", "noteable_type"=>"Issue", "note"=>"this is my note"}, "commit"=>"Add Comment", "namespace_id"=>"Nate", "project_id"=>"sample"}
Completed 200 OK in 60ms (Views: 0.3ms | ActiveRecord: 4.2ms)

what do i need to do to get notes/comments working again?

@lilnate22 Please post the output of sudo gitlab-ctl tail when you click on the Comment button
