Issue with registry.x86_64.bin

Dear Gstreamer List,

I am trying to debug a commercial application that uses Gstreamer. We are
running on a Centos 7 cluster with a variety of graphics cards (i.e. K80)
in an Openstack virtual environment.

 When the program runs for the first time on a machine, a considerable time
delay occurs (40+ minutes) before the program initializes, although
subsequent runs start immediately.

I have traced this delay to a file, ~/.gstreamer-0.10/registry.x86_64.bin
If you delete the file, we can trigger the very long delay when running the

I am not a Gsteamer developer, so would be very grateful if anybody could
advise me on how this file is created. We are very interested into why it
is taking so long to create. This could be a programming issue with the
commercial application, but it could also point to some very strange
interactions between Gstreamer and the virtual environment.

Are there any tools that we could use to generate this file to confirm that
this is in fact the problem?

Thanks for any assistance given
