|Platform||Intel x86_64||OS||Fedora||OS Version||29|
|Summary||0007860: Export fail with underruns|
|Description||Suddenly Ardour starts having problems with export to audio. A dialog says the disk cannot keep up with Ardour. Nothing in the log window, but the console shows:|
STE-008 Need 1024 total = 679
underrun for STE-008
STE-001 1 Need 1024 total = 679
underrun for STE-001 1
STE-003 Need 1024 total = 679
underrun for STE-003
and some more. total= value is always 679.
|Steps To Reproduce||Open Ardour and load project|
Session > Export > Export to Audio Files >
File format: BWAV 24 bit
TIme span: Session
The export starts, and about halfway a dialog appears that the disk cannot keep up with Ardour.
This is reproducible with this project and does not happen with other projects.

||The issue is reproducible when restored from the archive provided.|
A sudden as it started the issue seems to have disappeared. However, the following questions remain:
* Even if it was a (temporarily?) slow disk, how come the problem occurred consistently during a few days.
* During this period, a restored archive copy of the project encountered the same issues.
* During this period, no problems were encountered with other (earlier) Ardour projects.
* If it were random read errors, how come there were always 679 out of 1024 samples read on different audio files on different runs.
* The disk used is a network disk on a NAS. It typically does 100-250 MB/s which is more than sufficient to read audio files.
* All my Ardour projects reside on this disk.
