track plays fine, refuses to export it

My drum tracks refuse to export. They play fine in the editor.

This happens even when I check specific tracks.

Any ideas?

it had been an okay session up to that point. a couple of crashes but nothing major.

[niko@localhost ~]$ ardour2 --version Ardour/GTK 2.4.1 (built using 3243 and GCC version 4.3.0 20080404 (Red Hat 4.3.0-6))

pretty sure its a plug-in ‘crapping out’ (technical term). for some reason it seems to be more susceptible during the export process.

not a huge problem because of the rerouting possibilities, can always make it record elsewhere.
