Zotero just crashed after running out of memory.
Notes from IRC:
[14:08] <akosiaris> I think that's the first one zotero(3)(+0000000): HTTP POST noDoi=yesDoi&doi=10.2307%2F2458932 to http://www.jstor.org/action/downloadSingleCitationSec?userAction=export
[14:08] <akosiaris> &format=refman&direct=true&singleCitation=true
[14:08] <akosiaris> that got an out of memory error
[14:08] <akosiaris> well, maybe that one http://www.jstor.org/stable/2458932
[14:08] <akosiaris> not sure with zotero logging
[14:09] <akosiaris> seems like it was submitted multiple times
[14:09] <akosiaris> right before the out of memory error
